Claim:
An automotive airbag cover, characterized by comprising: a base material including a base material cleavage groove having a predetermined depth from a rear surface of the base material toward a top surface thereof; and a skin material overlapped and bonded onto the top surface of the base material in an integral manner; characterized in that a hardened layer solidified by penetrating thereinto a hardening agent made of an adhesive used for the bonding to the base material is provided in an entire surface of the skin material on a rear surface side thereof that is a bonding surface side to be overlapped and bonded onto the base material, a skin cleavage groove is provided on the rear surface side of the skin material at a position corresponding to that of the base material cleavage groove of the base material, and the skin cleavage groove is formed shallower than the depth of the hardened layer so as to produce, at a time of a cleaving action, stress concentration acting in an opening direction, at a groove bottom of the skin cleavage groove by way of the hardened layer, the hardened layer being subjected to a hardening process by the adhesive for bonding the base material to the skin material.
