Abstract
A solid electrolytic capacitor includes a base substrate, a capacitor element, a metal cap, an extractor terminal and an insulating member. The base substrate has electrical conductivity. The capacitor element is provided on the base substrate. The metal cap is coupled to the base substrate and covers the capacitor element. The extractor terminal passes through the base substrate, is coupled to an anode of the capacitor element, and includes a first conductive member acting as a core member and a second conductive member covering the first conductive member. The insulating member is provided between the base substrate and the extractor terminal. Electrical conductivity of the first conductive member is higher than that of the second conductive member. Thermal expansion coefficient of the second conductive member is less than that of the insulating member.
