Abstract:
The light-emitting apparatus (1) of the present invention includes: a storage case (12) that includes a base board (10) having a concave portion (10a) and a lid portion (11) covering the concave portion (10a); and a plurality of light-emitting elements (13) that are disposed on an inner surface (12a) of the storage case (12), an opening (11a) is formed in the lid portion (11), at least a part of the inner surface (12a) is a light-reflecting surface that wave-guides light emitted by the light-emitting elements (13) as light sources to a position directly underneath the opening (11), and a reflecting portion (15) that reflects the light emitted by the light-emitting elements (13) as the light sources toward the opening (11a) is formed directly underneath the opening (11a). Thereby, the light-emitting apparatus having a point light source with high brightness can be provided.
