PROBLEM TO BE SOLVED: To provide a gas flow rate control device for a gas range in which a characteristic of a pressure sensor 7 changes in response to the temperature change of the gas range, and fire power of a gas burner 7 varies. SOLUTION: A gas passage 11 connected to a gas injection nozzle includes a gas flow rate adjusting means 2 for adjusting a gas flow rate of fuel gas to the gas injection nozzle, and a pressure sensor 7 for detecting secondary pressure of the fuel gas in the gas passage in a downstream side of the flow rate adjusting means. The flow rate adjusting means changes opening of gas passage to increase or decrease the gas flow rate from minimum gas flow rate to maximum gas flow rate to determine setting fire power of the gas burner. By adjusting the flow rate adjusting means, the fuel gas of the minimum gas flow rate is made to flow to the gas passage and the secondary pressure detecting means detects the secondary pressure. Based on the detected secondary pressure, the opening of the flow rate adjusting means corresponding to the gas flow rate determining each setting fire power is corrected, and the fire power of the gas burner is adjusted with the corrected opening.
