摘要：
An electric discharge machining apparatus of the present invention includes a power supply, an electrode gap configured so as to be formed by an electrode and a workpiece, and an earth floating-capacitance current-suppressing coil configured to be inserted between the power supply and the electrode gap. Accordingly, the impedance in the charging path from the power supply to an interelectrode capacitance (an interelectrode parallel capacitor and an interelectrode parallel floating capacitance) can be decreased, and the impedance in the charging path to an earth floating capacitance can be increased, thereby enabling the electric current from the earth floating capacitance during discharge machining to be suppressed.
