Abstract
A light source unit for a vehicle lamp includes a light generating portion including a light source that emits excitation light, a light emitting layer constituted of an inorganic material and emitting generated light by irradiation of the excitation light, and a holding member that holds the layer; and a lens member that irradiates the generated light from the layer in a front direction in a vehicle-mounted state. The unit further includes a reflective portion disposed between the layer and the lens member, capable of reflecting a part of light from outside of the lens member, and capable of transmitting the generated light generated in the layer; or a light absorbing portion disposed between the layer and the lens member, and absorbing a part of a wavelength component among light from outside of the lens member being associated with the generated light.
