ABSTRACT:
A solid electrolytic capacitor having multiple capacitor elements and a lead frame is provided. Each capacitor element includes an anode part, a cathode part, an insulating part and at least one first slit. The cathode part is disposed opposite to the anode part. The insulating part is disposed between the anode part and the cathode part. The first slit is disposed at the anode part. The lead frame has an upper surface and a lower surface where the capacitor elements are stacked on. The lead frame includes an anode terminal part electrically connected to the anode part, and includes a cathode terminal part electrically connected to the cathode part. Specially, the anode terminal part includes at least one first projecting part, which projects toward the upper surface. The capacitor elements are stacked on the upper surface and the first slit is inserted into the first projecting part.
