Abstract

Disclosed is a two-color molded front cover of a vehicular lamp. The front cover includes a light transmissive resin portion, and a black resin portion integrally molded on a part of a peripheral edge portion (first surface) of the light transmissive resin portion. A cover portion formed by a part of the black resin portion is formed on a peripheral side portion (second surface) of the light transmissive resin portion which is adjacent to the peripheral edge portion. Since a non-uniform black resin portion is not formed on the peripheral side surface of the light transmissive resin portion, the appearance of the light transmissive resin portion of the front cover is improved.
