Abstract:
A front cover for a vehicle lighting fixture is attached to the front opening part of the vehicle lighting fixture having a lamp body and a light source installed in the lamp body. A part of the surface of the front cover opposed to the light source includes a heating element having a three-dimensional curved surface. The heating element includes a mesh pattern having intersections of a large number of grids formed of conductive metallic filaments and a first electrode and a second electrode formed at both opposed ends of the mesh pattern. The projection shape of the outline of the entire mesh pattern is formed in a rectangular shape having the longitudinal direction, for example, between the first electrode and the second electrode.
