A headlight for a vehicle includes a light source. The light source includes: a substrate; a light emitting diode chip; and a phosphor. The phosphor through which light exiting from a light emitting surface penetrates. The phosphor includes an exiting surface through which the light from the light emitting surface penetrates and exits. A first direction of the exiting surface corresponds to a height direction of a light distribution pattern by the light exiting from the exiting surface, and a second direction of the exiting surface corresponds to a spread in a lateral direction of the light distribution pattern. A dimension in the first direction of the exiting surface is smaller than a dimension in the second direction of the exiting surface.
