A capacitor has stacking capacitor elements, each of which contains a conductor plate, a first band being an insulator and disposed around the plate, a second band being an insulator and disposed around the plate so as to be substantially parallel to the first band, an insulating coating covering a region sandwiched between the first and second bands, a cathode layer formed on the insulating coating, and an anode containing the plate and formed on an outer side of at least one of the first and second bands. The cathode layers are elctrically connected to each other through paths each connecting in series the facing two cathode layers of the adjacent two elements and path(s) connecting in parallel the cathode layers to each other, and the anodes are electrically connected to each other through path(s) connecting in parallel the anodes to each other.

Stacked capacitor and method of fabricating the same

A surface-mount capacitor includes a multilayer capacitor structure formed by laminating plate-like capacitor elements each having anode lead portions at opposite ends thereof and a cathode portion at the center, an anode terminal connected to each anode lead portion via a strip-like plate, and a cathode terminal connected to the cathode portion. The anode and the cathode terminals and have a flat shape and are formed on a common plane as a substrate-mounted surface. A mold resin case has a bottom portion filling a gap between the anode and the cathode terminals and mechanically connecting the anode and the cathode terminals and sidewalls substantially perpendicular to the substrate-mounted surface. The anode and the cathode terminals have upper surfaces exposed on an inner bottom surface of the mold resin case to be connected to the anode lead portions and the cathode portion.
