PROBLEM TO BE SOLVED: To achieve improvement of the degree of freedom in design and the like.SOLUTION: A light source unit includes: a substrate 2 having connection parts 2b, 2b,...on both surfaces respectively; a plurality of light emitting bodies 3, 3 having light emitting diodes 3a, 3a provided as a light source and power supply parts 3b, 3b,... connected to the connection parts formed on both surfaces of the substrate respectively and supplying power to the light emitting diodes; and a socket 4 on which the substrate is mounted. The socket is replaceable with respect to a lamp body or a reflector 101, and a connector 5 connected to a power supply circuit is connected to the socket. As the light emitting bodies are mounted on both surfaces of the substrate 2 respectively, the substrate can be miniaturized. Also, as efficiency regarding arranging space of the light emitting bodies with respect to the substrate is high, the degree of freedom in design can be improved. |
