To provide a shock-absorbing material which has a weakly bonded portion with the bonding strength of a bonded portion being locally weakened, is broken at the weakly bonded portion when the external force of a predetermined value or more is applied thereto, and absorbs the external force by extracting sealed air, and also absorbs an impact force even after the weakly bonded portion is broken.
A shock-absorbing material X comprises a body 10 with air sealed therein, and auxiliary pockets 23 provided on the inner side of the body 10. The auxiliary pockets 23 have a passage P facing the outside air. Peripheral edges of the body 10 are adhered to each other so that air is sealed in first cavities formed between a first film 11 and a second film 12.
