A layered composite component includes a plate-shaped base member formed from a plastic material, a cover member layered on the base member, and a stitching. The cover member includes a plate-shaped main body extending along the base member such that the main body is spaced apart by a gap from the base member and projections projecting from an opposing surface of the main body opposed to the base member. The cover member is formed from a plastic material and is elastically deformable. The cover member includes a stitched portion linearly extending and including a portion on which the stitching is formed. The projections are not formed on the stitched portion, and the stitched portion includes a ridge extending along the stitching.
