ABSTRACT:
First and second capacitance elements are provided to have the same electric characteristics as each other. A first electrode of the first capacitance element is connected to a second electrode, which is not a counterpart electrode of the first electrode, of the second capacitance element, and a second electrode of the first capacitance element is connected to a first electrode of the second capacitance element. As a result, a capacitance value and a leak current do not change, even if positiveness and negativeness of a bias voltage applied to the connected capacitance elements are reverse.
