A solid electrolyte condenser includes two condenser components disposed along a first direction Z and connected in parallel. Each condenser component includes: a porous sintered body forming an anode; an anode wire having a portion being inserted into the porous sintered body; a dielectric layer covering the porous sintered body; and a cathode portion forming a cathode. The solid electrolyte condenser includes: a spacer, which is conductive and of which two ends in the first direction Z are respectively connected with the anode wires; an anode terminal, fixed to a side of the spacer that is opposite to the two condenser components; a cathode terminal, connected with each cathode portion at the two sides in the first direction Z; a sealing resin, covering the two condenser components; and an anode connection portion, fixed at the anode terminal of the spacer and formed along the first direction Z.

Solid electrolytic condenser and method of manufacturing the same

A capacitor element includes an anode chip body formed by sintering valve metal powder, an anode wire projecting from an end surface of the anode chip body, and a ring member made of a water-repellent thermoplastic synthetic resin and fitted around a root portion of the anode wire connected to the anode chip body. The ring member is fitted and attached to the anode wire. The ring member adheres closely to both of the anode chip body and the anode wire without a gap by thermally melting the ring member in its fitted state around the anode wire.
