A light emitting device can include a head portion including a surface including a convex portion, a back surface on the opposite side, and a through hole penetrating a tip surface of the convex portion and the back surface; a light-transmitting member including a surface and a back surface on the opposite side, the back surface including a first recess to be fitted to the convex portion; an adhesive bonding part of the surface of the head portion around the convex portion to the back surface of the light-transmitting member while the convex portion is fitted to the first recess and the first recess covers the through hole; a semiconductor light emitting element that emits light passing through the through hole for irradiation of the light-transmitting member; and an optical system condensing the light from the semiconductor light emitting element and locally irradiates the light-transmitting member with the light. |
