|20090243460||FILM-PROVIDED MOLDED PIECE, METHOD FOR AND APPARATUS FOR PRODUCING THE SAME - An electric connection part between a bulb and a terminal is masked without using a special masking material when a lamp unit is produced through a primary injection step of molding a lamp main body and a lens part while using a movable mold and a fixed mold, a film forming step of covering the lamp main body with a film, and a secondary injection step of uniting the lamp main body and the lens part together with a resinous material. The bulb is incorporated through a step set between the primary injection step and the film forming step. In the state in which the bulb is incorporated in the lamp main body, the surface of the top of the bulb is covered with a film, and a part hidden by the shadow of the film is masked, and hence electric insulation properties are secured.||10-01-2009|
