Abstract

In a chip type solid electrolytic capacitor, an anode terminal is provided with an anode terminal lower surface exposed from a package lower surface and an anode terminal end surface adjacent to the anode terminal lower surface and exposed from a first package end surface. The cathode terminal is also provided with a cathode terminal lower surface and a cathode terminal end surface. The anode terminal end surface is provided with an anode terminal dent surface upwardly extending from the boundary with the anode terminal lower surface. The anode terminal dent surface is plated. The cathode terminal end surface is also provided with a cathode terminal dent surface which is plated.
