PROBLEM TO BE SOLVED: To provide an electronic apparatus which enables downsizing and achieves good heat radiation performance thereby securing proper life.SOLUTION: A power supply device includes: a case; a transformer 34; a heat sink 2b; an aluminum electrolytic capacitor 35; and a heat insulation part 6. The case is formed by a resin. The transformer 34 is disposed in the case. The heat sink 2b is disposed along an outer surface 13s of the case, indirectly contacts with the transformer 34 through a heat radiation gel sheet 4, which is disposed contacting with the transformer 34, and the case. The heat sink 2b has heat conductivity higher than that of the resin forming the case and emits heat generated by the transformer 4 to the exterior. The aluminum electrolytic capacitor 35 is disposed in the case. The heat insulation part 6 is provided between the heat sink 2b and the case 1 so as to face the aluminum electrolytic capacitor 35 and blocks heat transmission from the heat sink 2b to the aluminum electrolytic capacitor 35. |
