PROBLEM TO BE SOLVED: To raise the design of the appearance, and improve the design freedom of the surface material body.SOLUTION: There is prepared a mold 5 that has a fixed mold 6 and a mobile mold 7. A first elongated protrusion part 83 that forms nearly half the second stitch forming concave streak groove 33 is provided in a molding surface 8a side end of a division surface 8b in a slide mold 8. The second elongated protrusion part 71 that forms nearly half the second stitch forming concave streak groove 33 and forms the second stitch forming concave streak groove 33 with the first elongated protrusion part 83 combined with the first elongated protrusion part 83 in a mold closed state is provided at the side end of the molding surface 7a of the dividing surface 7b in the mobile mold 7. After molding the flexibility surface material body 30 by filling the thermoplastic resin in the cavity Ca of the mold 5 in the mold closed state, the mold 5 is carried out mold open and the mold surface material body 30 is taken out of the mold 5, and then stitches St are applied to the second stitch forming concave streak groove 33 of the surface of the surface material body 30 by a sewing thread 4. |
