PROBLEM TO BE SOLVED: To provide a lamp including a heat radiation section capable of ensuring good heat radiation even if the heat radiation section is insufficiently fixed to a pedestal due to a loosening screw or the like.SOLUTION: A lamp comprises: a semiconductor light-emitting element; a pedestal that is plate-shaped and that has one principal surface on which the semiconductor light-emitting element is arranged; and a first heat radiation section and a second heat radiation section arranged on the other principal surface of the pedestal. The first heat radiation section includes a first base fixed onto the other principal surface, and the second heat radiation section includes a second base fixed onto the other principal surface of the pedestal while being distanced from the first base. The first base and the second base are thermally connected to each other by a heat conduction path without via the pedestal. |
