PURPOSE: An electronic gas meter is provided to effectively measure an amount of gas usage using one gas meter by installing low-pressure and high-pressure spraying devices in a gas passage of a body of the electronic gas meter. CONSTITUTION: An electronic gas meter includes a body(10) connected to gas pipes(100A,100B), a fixing member mounted on the body(10) in order to guide gas flow, an impeller(30) rotatably coupled to the fixing member, a housing(40) having a lead switch(45) for generating a signal by detecting a rotation of the impeller(30), and a casing(50). The body(10) is provided with connecting parts(10a,10b), which are closely coupled to the gas pipes(100A,100B). An inlet port(11) and an outlet port(12) are formed at an inner portion of the connecting parts(10a,10b). A central passage(13) is connected to an end of the inlet port(11). A protrusion is formed at an edge portion of an upper connection part.
