Provided is a lamp with an LED that can prevent snow from sticking or snow melted thereon from freezing. A lamp (10) includes: an LED module (11) serving as a light source; a heatsink (12); a heat transfer unit (13); a light distribution unit (14); a housing (15) with an opening; and a light-transmissive cover (16). The LED module (11) includes a plurality of LEDs, and an LED substrate having a mounting surface on which the plurality of LEDs are mounted. The heatsink (12) is arranged on the side of the LED substrate opposite to the mounting surface. The light distribution unit (14) is arranged on the light emitting side of the LED module (11). The LED module (11), the heatsink (12), and the light distribution unit (14) are arranged in the housing (15). The light-transmissive cover (16) is arranged in the opening of the housing (15). The heat transfer unit (13) includes a heat conduction section (13a) and a heat discharge section (13b), the heat conduction section (13a) being arranged so as to conduct heat from the heatsink (12), and the heat discharge section (13b) being arranged so as to be able to discharge the heat to the light-transmissive cover (16).
