The purpose of the present invention is to provide a vehicular lamp which creates light directed upward using a reflector that allows the light incident below the lower end of the lens to exit upward through a lens and which minimizes the uneven light distribution of the created light distribution pattern. The vehicular lamp according to the present invention includes: a semiconductor light source unit (20) including a light-emitting chip (21); a horizontally long lens (30) disposed in front of the light source unit (20); and a reflector (40) positioned between the lens (30) and light source unit (40) and disposed below the light-emitting chip (21) along a vertical direction. The reflector (40) includes a reflection surface (41) for creating a plurality of virtual focal points intersecting a vertical axis passing through the light emitting center O of the light-emitting chip (21). The distribution of light from the reflection surface (41) is controlled so that light is emitted from a light emitting surface (32) vertically below the optical axis Z of the lens (30). The lens (30) is formed such that, when a point light source is assumed on the optical axis Z, first direct light LM on the optical axis Z emitted from the point light source is distributed upward from the light emitting surface (32).

A vehicle lamp includes a light source unit for road surface drawing capable of forming a light source image longer in an upper and lower direction than a left and right direction of the lamp and a projection lens through which light forming the light source image is transmitted and which projects a predetermined light distribution pattern on a road surface. A light emitting surface or a light transmitting surface of the light source unit is disposed in a vicinity of a rear focal point of the projection lens. The light emitting surface or the light transmitting surface is inclined with respect to an upper and lower direction orthogonal to an optical axis of the projection lens.
