Disclosed is a solid electrolytic capacitor, comprising a capacitor element, an anode wire extended from a first side of the capacitor element in a predetermined length, and an anode lead frame formed as an anode terminal. The anode lead frame has a groove at a first end thereof for mounting an end portion of the terminal end of the anode wire thereon, and is mounted at a second end thereof on a PCB. A cathode lead frame is formed as a cathode terminal. This cathode lead frame has a first end attached to an external surface of the capacitor element and a second end mounted on the PCB. An epoxy case covers the capacitor element, the anode lead frame, and the cathode lead frame. The anode wire is welded to the anode lead frame by melting a portion of the anode lead frame in contact with an end portion of the anode wire positioned on the groove, using a heat source. This solid electrolytic capacitor is advantageous in that the heat transfer to the capacitor element during a welding step is minimized, the production process of the capacitor is simplified, and the capacitance of the capacitor element is enlarged by increasing the space occupied by the capacitor element within a limited space of the epoxy case.
