To provide a power supply device that has a fixing structure for improving the radiation of capacitors and a car on which such a power supply is mounted.
A PCU upper cover 310 is provided so as to cover a PCU casing 300 for storing a power supply unit. The PCU casing 300 and the PCU upper cover 310 are fixed by screws 320, 321. On the inside wall surface of the PCU casing 300, capacitor fixing portions 305 are integrally formed that fit the body contour of the capacitors 240#. On the partial areas of the PCU upper cover 310, capacitor fixing portions 315 are provided that have the shape corresponding to the body of the capacitors 240#. Each capacitor 240# is fixed by being sandwiched by the capacitor fixing portions 305 and 315. As a result, the radiating area of each capacitor 240# is increased so that the cooling performance of the capacitors can be improved.
