Abstract
A lamp capable of efficiently dissipating heat generated in a semiconductor light-emitting element is provided. A lamp which emits light includes: a mounting board on which a semiconductor light-emitting element is mounted; a first housing thermally coupled with the mounting board; and a second housing including a power receiving unit which receives power for causing the semiconductor light-emitting element to emit light. The first housing is disposed closer to an illuminated area than the second housing is, and includes a first exposed surface exposed at least to the illuminated area.
