する補正機能付き炎電流検出装置。 A burner, a sensing body disposed in a combustion flame generated by the burner, a power source that applies a predetermined voltage between the burner and the sensing body, and a sensor formed between the burner and the sensing body. A pseudo-circuit that performs an action equivalent to an electric circuit through which a flame current flows, and a correction unit that corrects the flame current by comparing the flame current and a pseudo-current when the power supply voltage is applied to the pseudo-circuit. A flame current detection device with a correction function is characterized in that the flame current is detected with high accuracy even if the power supply voltage fluctuates.
