MANUFACTURE OF SOLID-STATE ELECTROLYTIC CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing solid-state electrolytic capacitors wherein equivalent series resistance is reduced while tanδcharacteristics is improved. SOLUTION: A solid-state electrolytic capacitor 12 is manufactured by sintering powder of valve action metal mixed with binder to form a sintered body 1, and sequentially forming an oxide coat 4 and a cathode layer on the sintered body 1. The powder of valve action metal mixed with granular binder of particle size 50μm or smaller is used to form the sintered body 1.
