Abstract:
1. A solid electrolytic capacitor, comprising: a capacitor element with positive polarity therein, wherein an external surface of the capacitor element is surrounded with a cathode layer; an anode wire inserted into one end of the capacitor element; a cathode terminal electrically connected to the capacitor element by being positioned at one side of a lower part of the capacitor element; an anode terminal which defines a molding injection space on a top surface thereof and is electrically connected to the anode wire by being positioned at the other side of the lower part of the capacitor element; a conductive paste coated on the capacitor element and being thicker toward an inside of the capacitor element, thereby electrically connecting the capacitor element to the cathode terminal, and broadening a space between the capacitor element and the anode terminal; a molding unit which wraps an external surface of the cathode layer and is formed to expose bottom surfaces of the anode terminal and the cathode terminal; and a fixing film made of conductive epoxy which is closely coupled to a bottom surface of the conductive paste, wherein the molding unit is formed to wrap the capacitor element and the fixing film in a state of closely adhering the conductive paste and the cathode terminal to top and bottom surfaces of the fixing film, respectively.
