Abstract
A capacitor for use in microwave transistor, comprises a dielectric material layer and conductive layers covering both sides of the surfaces of the dielectric material layer. A plurality of points on the surface of one of the conductive layers are connected by conduction wires. Each of the conductive wires has a length less than .lambda..sub.0 /2.sqroot..epsilon..sub.r, where .lambda..sub.0 is the minimum wavelength of electric signals applied to the capacitor element, and .epsilon..sub.r is the dielectric constant of the dielectric material layer. The middle portion of each of the conductive lines is separated from the above-mentioned one of the conductive layers. The conductive wires prevent the capacitor element from becoming extremely inductive even when the frequency is high.
