In the gas cutoff valve control device, the alarm means issues an abnormality alarm in response to a gas leak detected by the inner pipe leakage testing means, and the gas cutoff valve control device outputs an abnormality detection signal, wherein the inner pipe leakage testing time of the inner pipe leakage testing means is controlled by the gas cutoff. The inner pipe leakage inspection means is provided with a timing means for counting time from the time when the valve is closed, and the inner pipe leakage inspection means drives an alarm means when a gas leak is detected within a predetermined time period of the inner pipe leakage inspection time measured by the timing means. The gas cutoff valve control device is also characterized in that it outputs an abnormality detection signal when a gas leak is detected even after a predetermined period of time has elapsed.
