In a gas meter, a measuring diaphragm is provided inside a measuring chamber, the measuring diaphragm is caused to reciprocate according to a gas pressure of gas flowing from a gas inflow port to the measuring chamber, and the reciprocation of the measuring diaphragm is interlocked with a valve mechanism and an integrating mechanism via a wing shaft and a crank mechanism. Here, the measuring diaphragm is formed in an elliptical shape which is horizontally long in the width direction of the gas meter.
