Solid electrolytic capacitor manufacturing method

A method of manufacturing a solid electrolytic capacitor chip, comprising

• mounting a solid electrolytic capacitor element on one surface (front surface) side of a cathode lead of a lead frame serving as a cathode terminal;
• electrically connecting an anode and a cathode of the solid electrolytic capacitor element respectively to an anode terminal and the cathode terminal of the lead frame;
• and
• injecting an exterior resin from a resin injection port of a mold by transfer molding so as to seal the solid electrolytic capacitor element with the exterior resin, in which the resin injection port is located at such a position that the exterior resin injected from the injection port branches and flows toward both the front surface side and the other surface (rear surface) side and of the lead frame,
• wherein the height and location of the injection port is adjusted so that an upper end of the injection port is located higher than a front surface of the lead on which a sintered body is placed, and that a lower end of the injection port is located lower than a rear surface of the lead.
