  Embodiments of a vehicle component according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. In addition, the thickness and film thickness of the base material in the drawings are illustrated differently from actual ones.

  FIG. 1 shows an embodiment of a vehicle component according to the present invention. Hereinafter, the configuration of the vehicle component in this embodiment will be described. In the figure, reference numeral 1 denotes a vehicle component in this embodiment. As shown in FIG. 1, the vehicle component 1 includes a synthetic resin base material 2, a first adhesive film 3 formed on the surface of the synthetic resin base material 2, and a surface of the first adhesive film 3. A reflective film 4 formed on the surface, a protective film 5 formed on the surface of the reflective film 4, a second adhesive film 6 formed on the surface of the protective film 5, and a surface of the second adhesive film 6. The colored coating film 7 is formed.

  The base material 2 of the synthetic resin is a base material for vehicle parts such as a reflector, an inner panel, an extension, a decorative board, and a housing. In this example, the base material 2 is made of polycarbonate (PC) or cycloolefin polymer (COP). Is.

  In this example, the first adhesion film 3 is formed by sputtering or vapor deposition of chromium or titanium, and the film thickness of the first adhesion film is 2 to 5 nm.

  In this example, the reflective film 4 is formed by sputtering or vapor deposition of aluminum or silver, and the thickness of the reflective film 4 is about 100 nm.
