1. A power supply device for converting power supplied from a power source to power to be supplied to a load and supplying the converted power to the load from an output terminal, the power supply device comprising:
a power converter to convert the power supplied from the power source to the power to be supplied to the load and to output the converted power to the output terminal;
a capacitor including a dielectric, two electrodes opposing each other with the dielectric in between, a case accommodating the dielectric and the two electrodes, a first terminal electrically connected to one of the two electrodes and exposed outside the case, and a second terminal electrically connected to the other one of the two electrodes and exposed outside the case, the capacitor being located in a circuit between the power converter and the output terminal;
a busbar to which the first terminal is fixed, the busbar electrically connecting the first terminal to the output terminal; and
an electrically conductive support to which the second terminal is fixed, and wherein the electrically conductive support receives a reference potential.
