         3 . The in-body image capturing device according to  claim 1 ,
 wherein the second fixing member is provided with a surface fastener, and   wherein the second fixing member is fixed to the first fixing member via the surface fastener.   
     
     
         4 . The in-body image capturing device according to  claim 1 , further comprising:
 a cannula having a tube-like structure into which the support tube is insertable,   wherein the support tube is indirectly fixed by the fixing tool in a state of being inserted into the cannula.   
     
     
         5 . The in-body image capturing device according to  claim 4 ,
 wherein the support tube is fixed to the cannula outside the body, and   wherein the fixing tool fixes the support tube by fixing the cannula to the body surface.   
     
     
         6 . The in-body image capturing device according to  claim 4 ,
 wherein the support tube is movable in an axial direction within a range that the length of the support tube allows, and is fixed to the cannula to be rotatable around an axis.   
     
     
         7 . The in-body image capturing device according to  claim 4 ,
 wherein the support tube is fixed to the cannula due to a biasing force.   
     
     
         8 . The in-body image capturing device according to  claim 4 ,
 wherein a fixing strength between the support tube and the cannula is greater than a joining strength between the support tube and the joining portion.   
     
     
         9 . The in-body image capturing device according to  claim 4 ,
 wherein the fixing strength between the support tube and the cannula is within a range of 5 N to 50 N.   
     
     
         10 . The in-body image capturing device according to  claim 1 ,
 wherein a cable holder which holds and fixes the cable to the support tube is provided, and the support tube or the cable is fixed to the outside of the body.   
     
     
         11 . The in-body image capturing device according to  claim 1 ,
 wherein a cable holder which holds and fixes the cable to the support tube is provided, and a cable holding strength of the cable holder is greater than a joining strength between the support tube and the joining portion.   
     
     
         12 . The in-body image capturing device according to  claim 11 ,
 wherein the joining strength is within a range of 3 N to 6 N.   
     
     
         13 . The in-body image capturing device according to  claim 11 ,
 wherein the fixing strength onto the body surface by the fixing tool is greater than the cable holding strength.   
     
     
         14 . The in-body image capturing device according to  claim 1 ,
 wherein a cable holder which holds and fixes the cable to the support tube is provided, and a cable holding strength of the cable holder is within a range of 5 N to 50 N.   
     
     
         15 . The in-body image capturing device according to  claim 4 ,
 wherein the cable holder which holds and fixes the cable to the support tube or a support tube holder which holds and fixes the support tube to the cannula, is provided, and the cable holder or the support tube holder has a function of blocking at least a part of a void between the support tube and the cannula.   
     
     
         16 . An accessory for a support tube of the in-body image capturing device according to  claim 4 , which has at least two functions among a function of fixing the cable to the support tube, a function of fixing the support tube to the cannula, and a function of blocking at least a part of the void between the support tube and the cannula. 
     
     
         17 . A fixing tool for the in-body image capturing device according to  claim 1 , which includes a flexible adhesion surface with respect to the body surface.
