Disclosed is a coin-type electric double-layered capacitor comprising a capacitor element, a lower cover for housing the capacitor element by impregnating the same with an electrolyte, an upper cover for sealing the opening of the lower cover through an insulating ring-shaped packing, an upper terminal plate having one end portion connected to the upper surface of the upper cover, and a lower terminal plate having one end portion connected to the outer surface of the lower cover and a through hole formed in the other end portion. The coin-type electric double-layered capacitor is constituted such that at least a portion of the through hole is not covered with the outer surface positioned on the bottom portion of the lower cover but is arranged as an opening.
