Abstract:
1. A solid electrolytic capacitor comprising: a capacitor element having a positive electrode lead wire protruding from a front end face of the capacitor element and a negative electrode layer provided at an outer periphery of the capacitor element; a positive electrode lead terminal electrically connected to the positive electrode lead wire; and a negative electrode lead terminal electrically connected to the negative electrode layer, wherein the capacitor element, the positive electrode lead terminal, and the negative electrode lead terminal are sealed with an exterior sealing element made of synthetic resin except for a part of the positive electrode lead terminal and the negative electrode lead terminal, and wherein the positive electrode lead terminal includes: the raised connecting piece and the positive electrode lead wire are joined by welding; the positive electrode lead wire is secured to the raised connecting piece in such a manner that the positive electrode lead wire is fitted in a dent of the raised connecting piece; and a fit-in amount of the positive electrode lead wire with respect to the raised connecting piece is 2/5 to ¾ of an outer diameter of the positive electrode lead wire.
