<p><P>PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture which is provided with a reflecting member having a silver-deposited reflecting face which can maintain high reflectivity not obtainable by an aluminum-deposited reflecting face, for a long period of time. <P>SOLUTION: The vehicular lighting fixture is provided with the reflecting member 60 in which a topcoat layer 64 which is a protective membrane is formed on a silver-deposited membrane 62 formed on synthetic resin-made base material 61 in a lighting room S, and the topcoat layer 64 is constituted of a transparent acrylic based resin formed by synthesizing monomer with glass transition temperature of 60°C or more. The topcoat layer 64 is adhered to the silver-deposited membrane 62, and restrains Ag atom constituting the silver-deposited membrane 62 from aggregation. Since the Ag atom in the silver-deposited membrane 62 is held in a homogeneously dispersed state without aggregation, and fine indentation is not generated on the silver-deposited membrane 62, the sliver-deposited membrane 62 does not have yellowing, light reflection factor is 95%, and lightness of the lighting fixture is increased. The sliver-deposited reflecting face 62a has an excellent appearance with decent light-colored yellowish silver based color tone which is different from that of the aluminum-deposited reflecting face. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
