On the periphery of a polygonal main body formed by alternately placing electrode plates and dielectric layers, the electrode plates being alternately first and second electrode plates from the bottom, a plurality of first terminal electrodes connected with the first electrode plate and a plurality of second terminal electrodes connected with the second electrode plate are alternately formed. The first terminal electrodes or second terminal electrodes are provided at the corners of the main body. And the first terminal electrodes lies after the second terminal electrodes in a peripheral direction in a plan view of the capacitor. This capacitor can have a large capacitor and a low impedance in a wide frequency region.

Capacitor

A thin-film capacitor in which a plurality of capacitor elements are arranged side by side, each capacitor element being constituted by a dielectric layer, a first electrode layer formed on the lower surface of said dielectric layer, and a second electrode layer formed on the upper surface of said dielectric layer, wherein among the neighboring capacitor elements, there are provided first terminal electrode layers for connecting the neighboring first electrode layers together, and second terminal electrode layers for connecting the neighboring second electrode layers together; said first terminal electrode layers and said second terminal electrode layers are so arranged as will not be overlapped one upon the other; and said first and second terminal electrode layers are provided with an external terminal, respectively. The capacitor can be easily mounted on an external board and has a low-inductance structure.

Thin-film capacitor

A thin-film capacitor having a first and a second capacitor element disposed on a substrate substantially on the same plane adjacent to each other and laterally spaced in a direction along the plane. Each capacitor includes a dielectric layer and two electrode layers formed on the upper and lower side of the dielectric layer, respectively. The upper electrode layer of the first capacitor and the lower electrode layer of the second capacitor are electrically connected, and lower electrode layer of the first capacitor and the upper electrode layer of the second capacitor are electrically connected, via connection terminal electrodes. A plurality of such thin-film capacitors may be laminated, or placed side-by-side on the substrate.
