Abstract
A vehicular lamp includes: a light-emitting element arranged face forward; and a translucent member arranged to cover the light-emitting element from its front side. The member has a horizontally oblong shape in a front view, and includes: a direct light control portion located near the optical axis and directly emitting light forward from a front surface of the member; reflected light control portions located both sides of the direct light control portion and internally reflecting the entered light on a rear surface of the member to form substantially parallel light directed forward and emitting the light forward from the front surface; and a curved-surface light incident area formed on the rear surface to allow light from the light-emitting element to enter as substantially parallel light with respect to a cross section parallel to the axis and a longitudinal direction of the member in the direction perpendicular to the cross section.
