A lamp comprises a light emitting module including a substrate and LEDs mounted on the substrate, a heat sink that is cylindrical and that discharges heat produced during light emission by the LEDs, a base provided at one end of the heat sink, a mounting member having a front surface whereon the light emitting module is mounted, and a circuit unit positioned partially in the heat sink, receiving power through the base and causing the light emitting element to emit light. The mounting member is in contact with the heat sink so that the heat produced during light emission is transmitted to the heat sink. The circuit unit includes a circuit board and a plurality of electronic components mounted on the circuit board. The circuit board or at least one of the electronic components is thermally connected to the mounting member through a thermally conductive member.
