Abstract
A vehicular lamp including a lens member between a light-emitting element () and a light guiding plate () in which emitted light from the light-emitting element () is incident on the rear end surface () and then emitted from the front end surface () to the front of the lamp. The lens member () allows a part of the emitted light, which travels in a direction close to an optical axis (Ax), to reach the light guiding plate () as diffusing light that diffuses in a horizontal plane and further allows the emitted light to reach the light guiding plate () as parallel light along the optical axis (Ax) in a vertical plane.
