Abstract: A vehicular lamp capable of ensuring adequate adhesiveness between the lamp body and the lens and airtightness in a lamp space as well as attractive appearance when a lamp is turned on, and reducing the non-radiating portion of the lens as much as possible. The vehicular lamp comprises a mounting means 17 provided on the extended section 15 of the lens 3 formed along the peripheral edge of the lens such that the projection 18 extending toward the center of the lens and an insert 19 contiguous to the projection are substantially L-shaped in cross section, and the mounting means 10 of the lamp body 2 corresponding to the extended section of the lens comprises the mounting groove 11, which is substantially C-shaped in cross section and into which the insert on the lens is adapted to be inserted, and a portion 12 contiguous to an open edge of the mounting groove and facing the projection on the lens.
