ABSTRACT:
A solid electrolytic capacitor that includes a capacitor element including a chip and an anode wire projecting from a first end face of the chip. The chip has a second end face opposite to the first end face and a side face between the first and second end faces. An anode lead is electrically connected to the anode wire and a cathode lead is paired with the anode lead. The capacitor also includes a safety fuse wire that has a first end electrically connected to the side face of the chip, and a second end electrically connected to the cathode lead. A resin package encloses the capacitor element, part of the anode lead, part of the cathode lead, and the fuse wire. An insulating layer is formed at least on the side face of the chip adjacent to the second end face thereof for contacting and supporting the safety fuse wire.
