Although an example of fixing is shown, stitching may be performed by overlapping the outer material 31, the core material 22, one end and the other end of the handle 23, and the band material 33 in this order. Alternatively, one end and the other end of the core member 22 and the handle 23 and the band member 33 may be sewn to the lining 32 (in this case, the lining 32, one end of the handle 23, and the like between the outer surface 31 and the lining 32). The other end, the core material 22, and the band material 33 are overlapped in the order, and the lining 32, the core material 22, the one end and the other end of the handle 23, and the band material 33 are overlapped. Alternatively, the core material 22 and the handle 23 can be fixed by stitching one end and the other end of the core material 22 and the handle 23 to one or both of the outer material 31 and the lining 31 without the band material 33. (In other words, one end and the other end of the core material 22 and the handle 23 may be fixed to at least one of the outer material 31 and the lining material 32.) In either case, the computer sewing machine can be sewn. The core material 22 and the handle 23 can be fixed.

  Further, the core material 22, the handle 23, and the band 33 may be omitted.

  Moreover, in the said embodiment, although the bag main body 21 showed the example which has 2 layer structure which consists of the outer fabric 31 and the lining 32, the bag main body 21 may consist of a single material | dough, or a bag main body. 21 may be a stack of three or more fabrics. In any of the above cases, polyester, nylon, or cotton fabric can be used as the fabric for forming the bag body 21.
