Patent ID: 7746198

Claim:
An electric circuit device comprising: an electric element; and a first conductive plate connected to the electric element, wherein the electric element includes: a second conductive plate including a plurality of flat plate members disposed in parallel to each other; a third conductive plate including a plurality of flat plate members respectively facing each of the flat plate members of the second conductive plate; a first dielectric disposed between each of the flat plate members of the second conductive plate and each of the flat plate members of the third conductive plate; a first electrode connected to one end side of the second conductive plate in a first direction which is in parallel to each of the flat plate members of the second conductive plate; a second electrode connected to the other end side of the second conductive plate in the first direction; a third electrode connected to the third conductive plate; and a fourth electrode connected to the third conductive plate; the first conductive plate is connected between the first and second electrodes in parallel to the second conductive plate; and a resistance of the first conductive plate between the portion connected to the first electrode and the portion connected to the second electrode is lower than that of each of the flat plate members of the second conductive plate between the portion connected to the first electrode and the portion connected to the second electrode.
