An airbag door is formed integrally with an instrument panel where an outer skin member 10, in which a foam layer 12 is bonded to an outer skin 11, is bonded and laminated to a substrate member 4, and a tear line for performing fracture and deployment when an airbag is in operation is formed at a door substrate member portion of a substrate member 4. An adhesive strength between the foam layer and the above-mentioned door substrate member portion is set as a peel strength of at least 10N/25mm width or more. In the above-mentioned outer skin member 10, an outer skin single body fracture strength is set to 1.4-12.0 MPa, an outer skin single body elongation at break is set to 200-600%, and a peel strength between the foam layer and the outer skin is set to a range of 10-50N/25mm width.
