摘要：
According to one embodiment, a lamp unit includes a light-emitting module, a housing, a lighting circuit, and a heat conductive sheet. The light-emitting module includes a light emitting portion having a semiconductor light-emitting element formed thereon. The housing includes a case opening in the direction of irradiation of light, and a base on a side of the case opposite from the direction of irradiation of the light. The light-emitting module is mounted on a surface of the base on the case side. A base surface is formed on an outer surface of the base on the side opposite from the case side, and a depressed portion is formed on the base surface. The lighting circuit is accommodated in the housing. The heat conductive sheet allows resilient deformation, and is disposed in the depressed portion.
