PURPOSE: A solid electrolytic capacitor is provided to increase the capacity of a capacitor by electrically insulating both terminals of the solid electrolytic capacitor and the bottom of the capacitor. CONSTITUTION: A capacitor(110) has an anode inside a solid electrolytic capacitor. The outer surface of the capacitor device is surrounded by a cathode layer. An anode wire is inserted into one side of the capacitor. A cathode terminal(130) is arranged on one side of the bottom of the capacitor. The cathode terminal is electrically connected to the capacitor. An anode terminal(120) comprises a molding injection space in the upper part of the terminal. The anode terminal is electrically connected with an anode wire(111). A molding unit(150) surrounds the outside of the capacitor. The molding unit exposes the bottom of the cathode terminal and the anode terminal.
