PROBLEM TO BE SOLVED: To provide a cushioning material which absorbs a large impact force, and can prevent a housed article form being damaged. SOLUTION: For this air bag-shaped cushioning material 10 comprising a raw material of a high gas permeability, in which a gas is sealed, weak bonded parts 110, 120, 130 which are constituted in such a manner that they may be broken by a specified force by weakening the bonding force than a bonding force of bonded parts, are formed at a proper location of the bonded parts 11, 12, 13 and when a sudden impact is received, first, the weak bonded parts 110, 120, 130 break, and the sealed gas escapes through the broken part, and thus, the external force is absorbed. |
