PURPOSE: To provide a low-impedance four-terminal solid electrolytic capacitor, which is capable of performing effectively absorption of noise at a region of a high frequency of 1MHz or higher, can be surface mounted and can be increased in capacity.
CONSTITUTION: A solid electrolytic capacitor uses a conductive high-molecular layer as an electrolyte. Anode external terminal connection parts 1-1 and 1-2 are respectively provided on both end parts of a metal substrate 1 and striplike input/output anode external electrode terminals 4 and 5 are respectively connected to the connection parts 1-1 and 1-2 in such a way that they are made to project in the right-angled direction to the substrate 1 and in the same direction from one side surface of the substrate 1. Moreover, striplike input/output cathode external electrode terminals 6 and 7 are respectively connected to the upper and lower surfaces of a capacitor part 2 in such a way that they are made to project in the same direction as that of the terminals 4 and 5 from one surface of the capacitor part 2 and after a packaging is performed, the terminals 4 and 5 and the terminals 6 and 7 are bent at right angles.
