The electric discharge machine comprises: a storage unit; a current-coordinate detection unit; an electric-discharge-voltage detection unit a penetration detection unit; and a calculation unit. The storage unit stores therein a penetration determination voltage, a penetration determining duration, and a first projecting amount. The current-coordinate detection unit detects a current position of the electrode. The electric-discharge-voltage detection unit detects a minimum voltage of the electric discharge for each predetermined period. The penetration detection unit determines the electrode has penetrated through the workpiece.
