Zusammenfassung:	PURPOSE: An ammonia gas sensor with flow cell structure introduced is provided to accurately detect ammonia gas by preventing bubble or vortex phenomenon on flowing of buffer solution. CONSTITUTION: A sensor includes a flow cell body(210); a passage(220); a working electrode installation opening(230); and an external reference electrode(240). The passage is formed to penetrate one side to the other side of the flow cell body and has an inlet(222) and an outlet(224) slantly formed on a middle part thereof. The working electrode installation opening is formed on an appropriate place of an upper part of the flow cell body for a working electrode(250) to be installed to. The external reference electrode is installed on an appropriate place of a lower part of the flow cell body for one end thereof to be exposed to an inside of the passage and keeps electric potential regular regardless of condition of samples.
