STACKED COMPOSITE COMPONENT

In a stacked composite component in which cushioning properties are conferred by the elastic deformation of multiple projections, the present invention prevents the sagging or lifting of the decorated surface regardless of the shape of the curve. Engaging projections (40) are provided on a covering material (24) that is located on the decorated surface side of a major curved section (12a), which curves so that the decorated surface side is concave. Because the projections are inserted into insertion holes (42) provided in the base material (20) and are fastened to the base material (20) so as not to slip out from the insertion holes (42), sagging, wrinkling, lifting, etc. of the covering material (24) is prevented regardless of the shape of the curve and product quality is improved.
