Description of the Related Art Conventionally, it is well known that an interior material for a vehicle or a house is manufactured by thermoforming a sheet of plastic or a thermoformed cloth into a three-dimensional structure having various curved surfaces, but it is generally widely used. By molding the plastic sheet alone, only a plastic sheet having a flat appearance, touch, and cold feeling can be obtained. On the other hand, there are leather products that are used because of their favorable texture, but in the case of processed leather products, since the leather itself lacks in shape retention, it is necessary to cut and sew to make it into a three-dimensional shape. The required shape is long and complicated, and the obtained shape is limited to a relatively simple shape. In order to solve such a drawback, a cloth or leather is also attached to the surface of the above-mentioned plastic sheet single-molded article, but in order to attach it along a solid curve sufficiently, the cloth or leather is It is necessary to have a method of pasting three-dimensionally shaped pieces by cutting and sewing in advance, which is insufficient in terms of shortening the process and the shape and appearance of the molded product.
