PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor which can reduce ESR (Equivalent Series Resistance) and improve heat resistance, and to provide its manufacturing method. SOLUTION: The capacitor is manufactured through a step wherein a U-shaped molding die, a side die having a lead wire hole, and a press upper punch and a press lower punch are used to form a part of a lead wire made of a valve-action metal into a shape like wave, a coil spring, a hook, or a slantly bent object, to bury it in the valve-action metallic powder, to erect it, and to form it by pressing; and a step wherein a porous anode body is manufactured by sintering. Thus, the surface area of the buried part of the lead wire is made large and an anchor effect is generated, resulting in improved drawing strength. COPYRIGHT: (C)2006,JPO&NCIPI
