ABSTRACT:
An electric potential fixing apparatus of the present invention is an electric potential fixing apparatus that is connected to a connection line (17) between two capacitances, the first capacitance (14) and the second capacitance (15) that is directly connected to the first capacitance, includes the first high resistance (3), the second high resistance (4) that is connected directly to the first high resistance, a voltage dividing unit that outputs electric potential divided by the first high resistance and the second high resistance to the output terminal, the third capacitance (8) that is connected in parallel to at least either of the first high resistance and the second high resistance, and a voltage supply unit (1) operable to maintain constantly electric potential of the connection line between the two capacitances (14) and (15), holding combined total electric charge quantity of the first capacitance and the second capacitance, and the output terminal of the voltage supply unit is connected to a signal line between the two capacitances.
