Capacitor element for solid electrolytic capacitor, process of making the same and solid electrolytic capacitor utilizing the capacitor element

摘要

A capacitor element includes an anode chip body formed by sintering valve metal powder, an anode wire projecting from an end surface of the anode chip body, and a ring member made of a water-repellent thermoplastic synthetic resin and fitted around a root portion of the anode wire connected to the anode chip body. The ring member is fitted and attached to the anode wire. The ring member adheres closely to both of the anode chip body and the anode wire without a gap by thermally melting the ring member in its fitted state around the anode wire.
