SOLID ELECTROLYTIC CAPACITOR AND ITS MANUFACTURING METHOD

PURPOSE: To prevent a position deviation of a lead terminal and a leakage current by a method wherein an opening end part of a casing is hermetically sealed by a sealing member made of rubber and the lead terminal of a capacitor element is led out from its through hole and an epoxy resin layer is formed on the upper face of the sealing member and a top end part of the lead terminal is bent for surface mounting. CONSTITUTION: Lead terminals 51, 52 of a capacitor element 7 are inserted and penetrated into a hole of a casing sealing member 10 made of rubber and the sealing member 10 is mounted and fixed to lead boss parts 61, 62 in a root portion of the lead terminals 51, 52. The capacitor element having the sealing member is received in a casing 92 and a side face near an opening part of the casing is curled to fasten the sealing member 10, whereby the opening part of the casing is hermetically sealed. Thereafter, an epoxy resin layer 11 is formed on an upper face of the sealing member. Further, when making it as a vertical chip for surface mounting, the lead terminals 51, 52 are inserted into a hole of a base made of plastic and penetrated and bent and a capacitor body is fixed to the base.
