PROBLEM TO BE SOLVED: To improve the insulation performance between a power-feeding side and a power-receiving side.SOLUTION: A light-source device includes a power-feeding-side case 21 housing a power-feeding coil 23 connected to an AC power supply 10, a light-source mounting portion 60 on which a light-source portion 70 is mounted, and a power-receiving portion 30 supplying power to the light-source portion 70. The power-receiving portion 30 includes a power-receiving coil 33 magnetically coupled to the power-feeding coil 23, and a power-receiving-side case 31 housing the power-receiving coil 33 and disposed adjacent to the power-feeding-side case 21. The power-receiving coil 33 is disposed adjacent to the power-feeding coil 23 by the power-receiving-side case 31 being disposed adjacent to the power-feeding-side case 21, and is noncontactly power-fed by the power-receiving coil 23 to which a voltage from the AC power supply 10 is applied. At least one of a power-feeding-portion-side opposite surface 22 of the power-feeding-side case 21 and a power-receiving-portion-side opposite surface 32 of the power-receiving-side case 31 has an insulating region 80 formed by an insulating material in a region corresponding to a position at which the power-feeding coil 23 and the power-receiving coil 33 are adjacent to each other. |
