PROBLEM TO BE SOLVED: To provide a power supply device capable of easily arranging a plurality of light emitting devices along a face, and easily supplying electric power to each of the light emitting devices even when the plurality of light emitting devices are arranged substantially with no clearance.SOLUTION: A power source rail 200 (power supply device) is composed of a rod-shaped insulating member. A surface of the insulating member is provided with grooves 212, 214, 216. Inner both side faces of the grooves 212, 214, 216 are provided with conductive members 222, 224, 226. A light emitting module unit 100 (light emitting device) has a power source terminal 162, a ground terminal 164, and a signal terminal 166. The power source terminal 162, the ground terminal 164 and the signal terminal 166 are respectively held by the conductive members 222, 224, 226. Thus the conductive members 222, 224, 226 can be respectively electrically connected with the power source terminal 162, the ground terminal 164 and the signal terminal 166, and can hold these terminals. |
