To provide an electronic gas meter capable of avoiding the situation where gas supply is broken, even though normal functional conditions in gas consumption equipment exist, in the gas consumption equipment with a very moderate flow rate change for the speed of gas.

This electronic gas meter 10 is provided at least with a flow rate computing part 21 for computing the flow rate of the gas in a metering point with a fixed time interval, a flow rate storage part 14 for storing the flow rate measured by the flow rate computing part 21 by the plurality of measuring points, a comparison part 23 for finding the difference value Rp between the flow rate QIp in the latest measuring point Pr and the flow rate QIs in a reference measuring point Ps, that is a measuring point that goes back by a fixed time M from the measuring point, immediately prior to the point Pr, and for comparing the difference value Rp with a prescribed threshold, and a flow change determination part 25 for determining the presence of the flow rate change of the gas, based on a comparison result by the comparison part 23.
