 wherein each of the holders has a pair of plated leg parts provided on opposite ends of the raised plated parts.    
   
   
       7 . The assembly unit according to  claim 1 , 
 wherein each of the holders has a raised plated part, a mounting hole which is provided in the raised plated part and in which each of the mounting parts is inserted, and at least one engaging pawl formed on the mounting part to prevent the holder from removing out of the mounting hole when the mounting part is inserted in the mounting hole.    
   
   
       8 . The assembly unit according to  claim 7 , 
 wherein each of the mounting parts has a raised piece for engaging with the mounting hole to prevent the holder from removing out of the mounting hole.    
   
   
       9 . The assembly unit according to  claim 1 , 
 wherein the holders are disposed close with respect to each other.    
   
   
       10 . The assembly unit according to  claim 4 , 
 further comprising a boss disposed on a wall surface at one end of the raised plated part of one holder of the adjacent holders and projecting toward a wall surface of the raised plated part of the adjacent holder to the one holder, and a concave in which the boss fits and provided on the wall surface of the adjacent holder.    
   
   
       11 . The assembly unit according to  claim 1 , 
 wherein the rectangular base includes a pair of thin plates and reinforced ribs disposed between the pair of thin plates and extending in parallel with intervals.    
   
   
       12 . The assembly unit according to  claim 1 , 
 wherein the rectangular base comprises a cardboard made of a plastic material, and    wherein the plastic material is polypropylene resin.    
   
   
       13 . The assembly unit according to  claim 11 , 
 wherein the mounting parts project generally perpendicularly to a direction where the reinforced ribs extend.    
   
   
       14 . The assembly unit according to  claim 11 , 
 wherein the mounting parts project generally in parallel with a direction where the reinforced ribs extend.    
   
   
       15 . The assembly unit according to  claim 11 , 
 wherein the holders are made of a waste material of a resinous molding.    
   
   
       16 . The assembly unit according to  claim 12 , 
 wherein the rectangular base is made of a semi-transparent material other than a white semi-transparent material.    
   
   
       17 . A method for assembling an assembly unit for transport, comprising the steps of: 
 preparing a base having a rectangular shape;    providing mounting parts to be disposed with intervals each other along opposite sides of the rectangular base and project from the opposite sides; and    attaching detachably holders to hold opposite ends of each of elongate articles to be held while spacing an intermediate portion of each of the elongate articles from a surface of the rectangular base.    
   
   
       18 . A transporting method of stacking and transporting the assembly unit as recited in  claim 1  in a plurality of sets in a box.
