An instrument panel has a base, an air bag door core, a skin, and a polyurethane foam body. The base has an opening for passing an air bag if the air bag inflates. The door core is arranged on the surface of the base, to close the opening. The skin has a breaking facility that defines an air bag door. The foam body fills a space between the base and the skin. The instrument panel is provided with a specific string member. The string member has a face made of a non-adhesive part that is non-adhesive with respect to the foam body and a face made of an adhesive part that is adhesive with respect to the foam body. The string member is arranged on the surface of the base along the breaking facility so that the foam body breaks always along the breaking facility, to surely and smoothly open the air bag door without scattering the foam body.
