<P>PROBLEM TO BE SOLVED: To provide a gas discrimination device discriminating combustible gas by a simple process without restricting a concentration range of the combustible gas. Ž<P>SOLUTION: This gas discrimination device supplies combustible gas which is a discrimination object to a first gas sensor 10A and a second gas sensor 10B, and acquires in time series, output from each gas sensor 10A, 10B during adsorption combustion. The device calculates each output integrated value respectively in each gas sensor 10A, 10B from the outputs acquired in time series, and calculates a ratio between each calculated integrated value. Then, the device compares the ratio between each calculated integrated value with integrated value ratio determination information for discriminating a specific combustible gas, to thereby discriminate the combustible gas having high adsorbability.
