Abstract
An aspect of the present invention provides a method of manufacturing a solid electrolytic capacitor. The solid electrolytic capacitor includes an anode made of valve action metal, a dielectric layer, a solid electrolytic layer, a cathode conductive layer, and a cathode terminal. The method forms the cathode conductive layer by forming a conductive paste and conductive adhesive between the solid electrolytic layer and the cathode terminal and then simultaneously hardening the conductive paste and the conductive adhesive.
