PROBLEM TO BE SOLVED: To solve a problem wherein data analysis, etc. are difficult when some problem is intended to be grasped by clarifying the problem in a gas meter since power goes off and stored data are lost if a battery power supply of a gas meter control part turns down. SOLUTION: In this gas meter, if a power supply part 6 turns down to cause the control part 2 to go off and stored data are lost, the reasonability of an interruption/alarm cause is made clear by a second group of data such as interruption occurrence cause/track record measured by a first measurement part 1, and it can be grasped what problems have occurred in the gas meter.
