Abstract

Provided is a lighting device which includes a lead frame embedded in a glass material and has high reliability. The lighting device has a structure in which a light emitting element is mounted in a recess portion formed on a surface of a glass substrate and a sealing material is provided to cover the light emitting element. The lead frame is embedded in the glass substrate so as to be exposed on a side surface of the glass substrate and a bottom surface of the recess portion. A portion of the lead frame which is exposed in the recess portion is electrically connected with the light emitting element. With the structure as described above, the durability of the lighting device is improved.
