Abstract
A capacitor element includes an anode body made of valve metal having a substantially-rectangular shape and having positive and negative portions separated in a first direction parallel to a short side of the rectangular shape, a dielectric oxide layer over the negative portion, a solid electrolyte layer over the dielectric oxide layer, and a negative electrode layer over the solid electrolyte layer. A capacitor includes at least one of the capacitor element, an insulating enclosure encapsulating the at least one capacitor element, an external positive electrode provided on an exterior of the insulating enclosure at a first long side of the rectangular shape and extending in a second direction parallel to the long sides, the external positive electrode being connected to the positive portion of the at least one capacitor element, and an external negative electrode provided on an exterior of the insulating enclosure at a second long side of the rectangular shape and extending in the second direction, the external negative electrode being connected to the negative electrode layer of the at least one capacitor element.
