PROBLEM TO BE SOLVED: To prevent fracture on the bonded surface of a bag from being generated even when receiving vibrations and impacts or the like at the time of transport or the like. SOLUTION: This bag made of a liquid crystal polymer is manufactured by bonding the end parts of a liquid crystal polymer film to each other through a thermally fusable polymer. Also, the bonded surface of the bag includes two layers or more of a heat-welding layer made of a heat-weldable polymer, and at the same time, the heat-welding layers are heat-welded to each other.
