Patent ID: 8217306

Claim:
A vehicle lighting device, comprising: (i) a lamp housing, which partitions a lamp room, and a lamp lens; (ii) a light illumination portion which is disposed in the lamp room, for illuminating light to an outside through the lamp lens; (iii) a wire heater which is provided, by means of transfer, at a portion through which light from the light illumination portion is permeated, among the lamp lens; (iv) an extension portion which is integrally provided by a predetermined length from the wire heater; and (v) a power feeding portion which is provided at a tip end part of the extension portion, for feeding a power current to the wire heater via the extension portion, wherein the wire heater is a transfer-type wire heater including: (a) a base film; (b) an adhesive which is provided on one face of the base film; (c) an electrically conductive member for heater, which is formed in a wire pattern on the other face of the base film, a power current being fed, thereby generating a heat; (d) a resist which is provided on the other face of the base film so as to cover the electrically conductive member for heater, at least the base film being cut in a pattern that follows the wire pattern of the electrically conductive member for heater and which is caused to adhere the adhesive to the lamp lens, thereby transferring the electrically conductive member for heater to the lamp lens, the extension portion including: (e) an extension film which is integrally provided by a predetermined length from the base film; and (f) an electrically conductive member for extension which is formed in a wire pattern on one face of the extension film, one end of which is electrically connected to the electrically conductive member for heater, an adhesive part to be adhered to the lamp lens being provided at a part of a face at a side opposite to the lamp lens, among the extension film, a rough portion being provided on the face at the side opposite to the lamp lens, among the extension film of the extension portion, the face being a portion other than the adhesive portion, the power-feeding portion including: (g) a power-feeding film which is integrally provided at a tip end part of the extension film; (h) a power-feeding electrically conductive member which is formed in a wire pattern on one face of the power-feeding film, one end of which is electrically connected to the electrically conductive member for extension; and (i) a connector which is electrically connected to the power-feeding electrically conductive member and is fixed to the lamp lens, together with the power-feeding film.
