Abstract
A high frequency generating device used in a plasma ignition apparatus according to an embodiment includes a high frequency output unit, an output control unit, a current detecting unit, and an abnormality detecting unit. The high frequency output unit outputs a high frequency. The output control unit shifts a state of the high frequency output unit from a non-output state to an output-ready state of the high frequency. The current detecting unit detects a current that flows through a power-supply path to the high frequency output unit. The abnormality detecting unit detects output abnormality of the high frequency in the non-output state when a value of a current detected by the current detecting unit in the non-output state exceeds a non-output threshold.
