Abstract:
1. A light emitting device comprising: a base portion including a surface, a back surface on an opposite side with respect to the surface, and a first through hole penetrating the surface and the back surface; a light-transmitting member fixed to the surface so as to cover the first through hole; a semiconductor light emitting element configured to emit light to pass through the first through hole and for the light-transmitting member to be irradiated with; an optical system configured to condense the light from the semiconductor light emitting element and locally irradiate the light-transmitting member with the light; and a foil body including a second through hole for light emitted from the light-transmitting member to pass through and which has elasticity, the light-transmitting member being sandwiched between the foil body around the second through hole and the base portion with part of the light-transmitting member exposed from the second through hole.
