Abstract: A nitride semiconductor light emitting device includes a nitride semiconductor light emitting element and a package in which the nitride semiconductor light emitting element is accommodated. The package includes a base table in which openings are formed, a cap defining an accommodation space for accommodating the nitride semiconductor light emitting element together with the base table, lead pins passing through the openings and electrically connected to the nitride semiconductor light emitting element, and insulating members embedded in the openings to insulate the base table from the lead pins. At least parts of the insulating members which are located on an accommodation space side are made of a first insulating material containing no Si—O bond.

Abstract: A light source device includes: a semiconductor light-emitting device including a flat-shaped base having a first main surface on a first side and a second main surface and a semiconductor light-emitting element disposed on the first side; a first fixing component having a first through-hole and a first pressing surface that presses the first main surface; and a second fixing component having a second through-hole and a second pressing surface that presses the second main surface. The base is fixed between the first and second pressing surfaces by an engagement between a first inner surface surrounding the first through-hole of the first fixing component and a second outer surface of the second fixing component. A distance between the first and second pressing surfaces is smaller than or equal to a thickness of the base, and a void is formed lateral to the base between the first and second pressing surfaces.
