Claim 7:
8. A method for manufacturing a layered composite component, wherein the layered composite component includes a plate-shaped base member formed from a plastic material, a cover member layered with the base member, and a stitching, the cover member includes a plate-shaped main body and projections, the main body extends along the base member such that the main body is spaced apart by a gap from the base member, the projections project from an opposing surface of the main body opposed to the base member, and the cover member is formed from a plastic material and is elastically deformable, the stitching is formed by a sewing thread on the main body, the cover member includes a stitched portion linearly extending and including a portion of the opposing surface 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, the method comprising:
as a sewing apparatus configured to form the stitching, using a sewing apparatus including two rising plates extending from an edge of a thread plate defining a thread hole so that the two rising plates extend parallel in a direction in which a sewing subject is fed; and
when the ridge is fitted to a gap between distal ends of the two rising plates, forming the stitching with the sewing apparatus sewing the stitched portion while feeding the cover member in one direction, wherein
the ridge projects toward the base member,
the ridge is configured to come directly into contact with the base member as a gap between the base member and the main body is reduced, and
the ridge is one of two ridges and the two ridges are arranged one on each side of the stitching.
