ABSTRACT:
Disclosed herein is a solid electrolyte capacitor with organic semiconductor which comprises a capacitor element, a solid electrolyte layer formed by heating and melting TCNQ complex salt, impregnating the TCNQ salt into the capacitor element and thereafter cooling and solidifying the same, a powder coating layer formed to cover an upper portion of the capacitor element through a clearance, and a sealing resin layer covering the powder coating layer for sealing the capacitor element.
Since the powder coating layer is formed on the upper portion of the capacitor element through a clearance, it is possible to reduce influence exerted on the element by contraction or expansion caused by thermal stress which is applied in a soldering step. Consequently, it is possible to suppress increase of a leakage current.
