Abstract
The instant disclosure relates to a stacked-type solid electrolytic capacitor capable of increasing welding effect and a manufacturing method of the same. The stacked-type solid electrolytic capacitor includes a plurality of solid electrolytic capacitor units, each of which has an anode part and a cathode part connected to the anode part, characterized in that the anode part is formed with at least one buffering via-hole in a welding area thereof. When each of the anode parts is compressed in a welding process, the volume of the corresponding buffering via-hole decreases accordingly. Therefore, the soldering performance of the anode part solid electrolytic capacitor is enhanced and the connection stability is increased.
