PROBLEM TO BE SOLVED: To divide and integrate the gas flow rate of a plurality of gas appliances belonging to the same flow rate division, and further to perform integration as the gas flow rate of one gas appliance even if one gas appliance uses a plurality of flow rate sections. SOLUTION: The gas meter comprises a flow rate computing means 12 for computing gas flow rate per unit time; an integration section 13 for integrating the entire gas flow rate by integrating gas flow rate per unit time computed by the flow rate computing means; a flow rate division determining section 14 for judging which flow rate division of the flow rate division being divided into a plurality of portions the gas flow rate per unit time computed by the flow rate computing means 12 belongs to; and a flow rate division table 15, where a counter for integrating the gas flow rate of the flow rate division and the set amount of integration to the counter are set. Further, the gas meter has a counter integration section 17 that does not integrate in the counter for the flow rate division when the gas flow rate flowing in the flow rate division determined by a flow rate division determining section is less than the set amount of integration, and adds the set amount of integration to the counter in the flow rate division when the gas flow rate is equal to or more than the set amount of integration for integration.
