         2 . The packaging body according to  claim 1 ,
 wherein the packaging materials include
 two first packaging materials whose corner portions are arranged diagonally on one side, and 
 two second packaging materials whose corner portions are arranged diagonally on the other side, 
   a first piece and a second piece of a first packaging material have a double structure including an inner piece and an outer piece arranged outside the inner piece with a gap therebetween, and   a second packaging material has a first piece inserted into a gap of one of adjacent first packaging materials and a second piece inserted into a gap of the other adjacent first packaging material.   
     
     
         3 . The packaging body according to  claim 2 ,
 wherein the inner piece and the outer piece of the first packaging material are connected by a rail portion that is provided in the gap and that extends along the approach and separation direction, and   the first piece and the second piece of the second packaging material are formed with a slit that extends along the approach and separation direction and into which the rail portion is inserted.   
     
     
         4 . The packaging body according to  claim 3 ,
 wherein a wide portion is formed at an end part of the rail portion of the first packaging material, and   a step against which the wide portion abuts is formed at an opening-side end part of the slit of the second packaging material.   
     
     
         5 . The packaging body according to  claim 3 ,
 wherein the rail portion of the first packaging material connects the inner piece and the outer piece such that the outer piece is movable in an up-down direction relative to the inner piece, and   the packaging body includes a lock mechanism that locks sliding of the second packaging material with respect to the first packaging material in a case where the outer piece moves upward relative to the inner piece.   
     
     
         6 . The packaging body according to  claim 5 ,
 wherein the lock mechanism is provided in the gap, and   in a case where the outer piece moves upward relative to the inner piece, a lower-protruding upper serrated portion provided on an upper edge portion of the inner piece of the first packaging material engages and locks with an upper-protruding lower serrated portion provided on an upper edge portion of the second packaging material.   
     
     
         7 . The packaging body according to  claim 1 ,
 wherein a handle portion is provided at an intermediate portion in an up-down direction of each of the corner portions of the four packaging materials.   
     
     
         8 . The packaging body according to  claim 7 ,
 wherein the handle portion is configured such that a plate-like member having an L-shape in plan view is joined to the corner portion.   
     
     
         9 . A packaging box comprising:
 the packaging body according to  claim 1 ;   a bottom member that closes a lower opening portion of the packaging body; and   a lid member that closes an upper opening portion of the packaging body.   
     
     
         10 . A packaging box comprising:
 the packaging body according to  claim 2 ;   a bottom member that closes a lower opening portion of the packaging body; and   a lid member that closes an upper opening portion of the packaging body.   
     
     
         11 . A packaging box comprising:
 the packaging body according to  claim 3 ;   a bottom member that closes a lower opening portion of the packaging body; and   a lid member that closes an upper opening portion of the packaging body.   
     
     
         12 . A packaging box comprising:
 the packaging body according to  claim 4 ;   a bottom member that closes a lower opening portion of the packaging body; and   a lid member that closes an upper opening portion of the packaging body.   
     
     
         13 . A packaging box comprising:
 the packaging body according to  claim 5 ;   a bottom member that closes a lower opening portion of the packaging body; and   a lid member that closes an upper opening portion of the packaging body.   
     
     
         14 . A packaging box comprising:
 the packaging body according to  claim 6 ;   a bottom member that closes a lower opening portion of the packaging body; and   a lid member that closes an upper opening portion of the packaging body.   
     
     
         15 . A packaging box comprising:
 the packaging body according to  claim 7 ;   a bottom member that closes a lower opening portion of the packaging body; and   a lid member that closes an upper opening portion of the packaging body.   
     
     
         16 . A packaging box comprising:
 the packaging body according to claim  8 ;   a bottom member that closes a lower opening portion of the packaging body; and   a lid member that closes an upper opening portion of the packaging body.   
     
     
         17 . A packaging box comprising:
 the packaging body according to  claim 1 ;   a bottom member that closes a lower opening portion of the packaging body; and   a lid member that closes an upper opening portion of the packaging body,   wherein a dimension of the packaging body is adjusted to match an outer shape of an object to be packaged.   
     
     
         18 . A packaging box comprising:
