PROBLEM TO BE SOLVED: To obtain a cold insulating effect or a heat insulating effect while carrying a bag body on the back by holding a cold insulator or a heat insulator in the bag body such as a knapsack carried on the back. SOLUTION: This bag body is constituted to be carried on the back and to be formed with a holding means for holding the heat insulator or cold insulator. The back body can be various bag-like bodies such as the knapsack, a caddie bag and a satchel. Various means such as a cord, a belt, a chain and a hook can be used as a means for carrying the bag body on the back. A heat storage material with large specific heat, or a material with heat absorbing action or heat generating action can be used as the heat insulator or cold insulator.
