Abstract

According to one embodiment, a lamp apparatus includes a light-emitting module, housing, and a lighting circuit. The light-emitting module includes a light-emitting element. The housing opens in the direction of irradiation of a light beam and having a cap on a side opposite from the direction of irradiation of the light beam. The cap is provided with a light-emitting module mounting portion projecting in the direction of irradiation of the light beam and the light-emitting module is mounted on the light-emitting module mounting portion. The lighting circuit is accommodated in the housing.
