With such a configuration, it is possible to prevent the decorative film 27 from being peeled off and torn at the inner edge 24e portion of the door edge frame 24 of the urethane foam 29.
  • a reinforcing layer 31 is provided on the surface of the decorative urethane film 27 that has been subjected to hairline hairline processing on the urethane foam side.
  • the decorating film 27 is formed with the polyethylene terephthalate film. Since the polyethylene terephthalate has high mechanical strength, the decorative film 27 itself is torn due to the secular change accompanying the thermal contraction of the foamed urethane 29, and the peeling of the adhesion of the decorative film 27 to the foamed urethane 29 from the torn part is aged. Can be prevented from progressing automatically. Thereby, the reliability of the maintenance of the adhesive strength between the urethane foam 29 and the decorative film 27 and the adhesive strength between the urethane foam 29 and the glass plate 25 can be ensured.
