An automobile airbag door includes a base member, a cover member, which is bonded to the surface of the base member, and a tear line, which is formed in the back side of the base member. The tear line is configured to be a starting point of tearing when the base member is pressed by an airbag being deployed and inflated. The cover member includes a three-dimensionally knitted cushion layer. The three-dimensionally knitted cushion layer includes a top-side knitted fabric layer, a back-side knitted fabric layer bonded to the surface of the base member, and a connection layer, which is configured by connecting strands connecting the back-side knitted fabric layer and the top-side knitted fabric layer to each other. The mass per unit area of the back-side knitted fabric layer is set to be in the range from 150 g/m2 to 300 g/m2.
