Abstract
The air bag cover has a skin layer on the surface side of the cover and a core on the back surface side of the cover. The cover is disposed so as to cover an air bag. The air bag cover has a breakable portion which is broken when the air bag expands. The breakable portion is formed by providing a continuous or intermittent concave portion on the back surface side of the air bag cover. A fragile layer lower in tensile strength than the skin layer is fused to the back surface side of the skin layer.
