Light source unit for vehicular lighting tool and vehicular lighting tool

A light source unit for a vehicle lamp comprising:

• a light generating portion including
• a light source that emits excitation light,
• a light emitting layer that is constituted by using an inorganic material, and emits generated light by irradiation of the excitation light, and
• a holding member that holds the light emitting layer;
• a lens member that irradiates the generated light from the light emitting layer in a front direction in a vehicle-mounted state;
• and
• a reflective portion that is disposed between the light emitting layer and the lens member, is capable of reflecting a part of light from outside of the lens member, and is capable of transmitting the generated light generated in the light emitting layer,
• wherein the reflective portion is formed on the lens member.
