Abstract
A lamp unit includes a light source including a plurality of light emitting elements provided in a common substrate; a projection lens that projects light emitted from the light source toward a front of the lamp unit to form a required light distribution pattern; and a light-transmitting body disposed between the light source and the projection lens and that forms a projection image by controlling transmission of light emitted from the light source. The light transmitting body includes a plurality of incident portions that causes light emitted from each of the plurality of light emitting elements to be incident, and the light transmitting body and the substrate are supported by a lens holder that supports the projection lens.
