A capacitor array that includes a plurality of solid electrolytic capacitor elements, a sheet-shaped first sealing layer, and a sheet-shaped second sealing layer. The plurality of solid electrolytic capacitor elements include an anode plate, a porous layer, a dielectric layer, and a cathode layer. Each of the solid electrolytic capacitor elements are partitioned from each other by a slit-shaped removal part and have a first main surface and a second main surface.
