Method of manufacturing solid electrolytic capacitor, and solid electrolytic capacitor

Provided are a solid electrolytic capacitor manufacturing method and solid electrolytic capacitor with which it is possible to more reliably and simply achieve insulation between a capacitor element and a terminal plate with a sealing resin. A capacitor element is formed having a negative electrode part in which a portion of the surface area of a valve metal is enlarged and a dielectric oxide film layer, a solid electrolyte layer, and an electrode extraction part are formed, and a positive electrode part in which an electrode extraction part is formed in a portion of the valve metal. A positive electrode electrode plate and a negative electrode electrode plate are positioned in the same plane with a gap maintained therebetween, with an insulating resin interposed in the gap, forming a terminal plate. Prior to bringing the capacitor element and the terminal plate together, an uncured sealing resin is positioned upon the positive electrode electrode plate of the terminal plate, and a conductive bonding agent is
