Abstract:
1. A surface-mount type electrolytic capacitor comprising: a capacitor main body having anode lead portions at end portions and a cathode portion at a center portion; anode terminals connected to the anode lead portions; a cathode terminal connected to the cathode portion; and an exterior case for armoring the capacitor main body, the anode terminals, and the cathode terminal, wherein the exterior case includes a box type resin case and an exterior case cover, wherein the resin case includes the anode terminals and the cathode terminal at a bottom portion thereof and is open upward, and wherein the exterior case cover covers a top and at least a part of an outer surface of a side wall of the resin case, the exterior case cover having a convex portion formed on an inner surface of a ceiling and a concave portion which is disposed between an inner surface of a side wall of the exterior case cover and the convex portion, wherein an upper end portion of the side wall of the resin case is fitted into the concave portion between the inner surface of the side wall of the exterior case cover and the convex portion, and wherein the capacitor main body is pressed by a lower surface of the convex portion, and wherein the convex portion of the exterior case cover is formed from an elastic member and is connected to the exterior case cover.
