PROBLEM TO BE SOLVED: To provide a gas leakage alarm with an incomplete combustion detection function, capable of surely detecting incomplete combustion. SOLUTION: This gas leakage alarm with the incomplete combustion detection function 1 has an LP gas leakage determination means 3a for determining whether an LP gas concentration detected, based on a sensor output from an LP gas sensor 5 comes to an LP gas alarm determination concentration stored in a storage means 7 or more; an LP gas leakage alarming means 8a for issuing an LP gas leakage alarm, when the LP gas concentration is determined to come to the LP gas alarm determination concentration or more; an incomplete combustion determination means 4a for determining whether an incomplete combustion gas concentration detected, based on a sensor output from an incomplete combustion gas sensor 6 comes to an incomplete combustion determination concentration or more; and an incomplete combustion alarming means 8b for issuing an incomplete combustion alarm, when the incomplete combustion gas concentration is determined to come to the incomplete combustion determination concentration or more. The alarm is provided with a gas diffusion means 9 for making the ambient gas diffuse. COPYRIGHT: (C)2009,JPO&INPIT
