見た場合には極性を認識することが出来なかった。In this conventional chip-type solid electrolytic capacitor, the stand-off portion 3 has the same shape on the anode lead terminal 1 side and the cathode lead terminal 2 side. The polarity could not be recognized when viewed from the side of the mounting surface equipped with.

ず、実装に要するコストも大きいと言う欠点があった。Therefore, in order to discriminate the polarity, the surface portion, which is the opposite surface of the standoff portion, is marked to indicate the polarity. However, if the polarity display is reversed or not marked in the marking process of the polarity display, the true polarity that matches the contents of the product cannot be discriminated, and therefore the electrical mounting side is There was a drawback that a reverse voltage was applied incorrectly when checking the characteristics. In addition, at the time of mounting, it is necessary to align the polar directions of the sticks and the embossed tape, which makes it impossible to perform bulk mounting, and there is a drawback that the cost required for mounting is high.

FIG. 1 is a vertical sectional view and a plan view seen from a mounting surface of an embodiment of the present invention. As shown in the figure, the solid electrolytic capacitor element 5, the anode lead terminal 1 and the cathode lead terminal 2 are connected by resistance welding and a conductive adhesive 6, respectively, and then molded with a molding resin 7. At this time, as for the shape of the standoff portion 3 on the mounting surface, the standoff end on the anode side was arcuate and the standoff end on the cathode side was square.
