Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a water meter capable of providing countermeasures against unauthorized use of applying an external magnetic field for the purpose of reducing a water charge. SOLUTION: This water meter having a flow measuring part 120 for detecting the rotational speed of a waterwheel generating the rotational speed proportional to a flow rate by a magnetic sensor is provided further with a magnetic sensor 160 for detecting the magnetic field from an outside, and displays a weighed amount using a flow amount set in advance that is a value set in advance as the flow rate, when the magnetic sensor detects the magnetic field from the outside.
