    • To enable accurate detection of ion balance with a simple configuration, thereby enabling small size and reduction of a manufacturing cost, and detection of the ion balance near the surface of an object to be discharged. An ion balance sensor includes an antenna 20 charged with positive ions or negative ions, and a normally-on type MOSFET 11 in which a gate electrode G is connected to the antenna 20, an ion balance-detecting resistance R is connected between a grounded source electrode S and the gate electrode G, and a DC power source VDS and a load resistance RL are serially connected between the source electrode S and a drain electrode D. A voltage of the gate electrode G is changed due to a voltage drop by a current flowing between the charged antenna 20 and an earth via the ion balance-detecting resistance R, and a change of drain current due to the voltage of the gate electrode G is detected, thereby detecting positive and negative balance of ions used for charging the antenna 20.

    • To provide a corona discharge ionizer that makes it possible to use a piezoelectric transformer by adding an effective ion balance function with a simple structure without applying particular changes to the structure, and that realizes noise reduction. In a corona discharge ionizer 10, a control electrode 6 is disposed in a cylindrical portion of an air supply pipe 2 which also functions as a shield body and at a location where ions are balanced. When a cylindrical inner diameter of the air supply pipe 2 is defined as Ds and an annular outer diameter of the control electrode 6 is defined as Dc, 2Dc
