Abstract
In a automotive headlamp having a discharge bulb as a light source, a lighting circuit receiving chamber is formed in the rear of a lamp body, a discharge bulb lighting circuit is fixed in the lighting circuit receiving chamber through resin molding, and an inner flange-like guide portion is formed in the lighting circuit receiving chamber to act as a reference member to set a liquid surface position of poured molten resin in pouring the resin. Also, the inner flange-like guide portion abuts against the surface of the molded resin portion to thereby prevent the molded resin portion from separating from the lighting circuit receiving chamber.
