A vehicle lamp is mounted on vehicles such as automobiles. The lamp has an inner chamber constructed by a lamp housing and a lens, respectively having long shapes. In the chamber, there is a long light source fixing face member on which plural light sources are fixed. All light sources or electric bulbs are neatly fitted to convex or concave guide portions. Circuit patterns are printed on an inner face of the housing. Terminals of the light sources come into contact with the circuit patterns. The housing is made of particular synthetic resin having a good heat conductivity, so that no heat is accumulated in the chamber.
