Method for manufacturing a solid electrolytic capacitor

摘要

A solid electrolytic capacitor comprises an anode body made of a valve action metal the surface of which is coated with an anodically oxidized film, a manganese oxide layer formed thereon through repeatedly dipping, into a high viscosity slurry of manganese oxide producing solution consisting of Mn(NO3)2-Mn(CH)2-NH4NO3-H2O followed by thermal decomposition, and a cathode layer formed thereon. Through the improvement of said solution a required amount of uniform and dense manganese oxide layer is produced with a minimum number of repetitions of the above process so that a solid electrolytic capacitor having an improved characteristic can be provided.
