Abstract: An electrolytic capacitor includes a capacitor element, a case housing the capacitor element, and a first heat radiation layer having an insulating property. The first heat radiation layer covers at least part of the capacitor element. A thermal conductivity λC of the case in a thickness direction is greater than or equal to 1 W/m·K. A thermal emissivity ε1 of the first heat radiation layer is greater than or equal to 0.7.
