To provide a gas meter capable of displaying an integrated value of an electric power output of a built-in fuel cell, and capable of enhancing convenience for a charge system for gas sale by a gas provider.
This gas meter is provided with the fuel cell 1 for generating electric power by using gas, a control part 3 for detecting and integrating the electric power output of the fuel cell 1 and for detecting and integrating a gas flow rate of a gas flow detector 2, and a display means 4 for displaying the integrated value of the detected electric power output of the fuel cell 1, and the integrated value of the detected gas flow rate in the gas flow detector 2. The display means 4 for displaying inherently measured information of the gas flow rate is used in common, for displaying the integrated value of the electric power output of the fuel cell 1, so as to enhance the convenience for the charge system for the gas sale by the gas enterprise.
