Light emitting device and vehicle lamp

摘要

A light emitting device (10) includes: a base portion (26) including a surface (32), a back surface (34), and a first through hole (H1) penetrating the surface (32) and the back surface (34); a light-transmitting member (12) fixed to the surface (32) so as to cover the first through hole (H1); a semiconductor light emitting element (14) emitting light to pass through the first through hole (H1) and for the light-transmitting member (12) to be irradiated with; an optical system for condensing the light from the semiconductor light emitting element (14) and locally irradiate the light-transmitting member (12) with the light; and a foil body (20) including a second through hole (H2) for light emitted from the light-transmitting member (12) to pass through and has elasticity, the light-transmitting member (12) being sandwiched between the foil body (20) around the second through hole (H2) and the base portion (26) with part of the light-transmitting member (12) exposed from the second through hole (H2).
