PROBLEM TO BE SOLVED: To provide a gas supply system to monitor operation of a cut off part and discriminate a stop of unprepared supply of gas caused by malfunction of the cut off part itself. SOLUTION: A gas supply route is formed such that a high pressure vessel filled with gas is positioned on the input side and a connection part 50 to a gas demander is positioned on the output side. The gas supply route comprises a pressure reducing part 12 on the primary side and a pressure reducing part 13 on the output side which are arranged on the input side and the output side: a heatexchange part 14 arranged between the pressure reducing parts 12 and 13; an emergency cut-off part 15 to arranged on the gas discharge side of the heatexchange part 14 and cutting off the feed of gas to the pressure reducing part 12 on the primary side by a discharge pressure higher than a given pressure; and an alarm part 19 located in a supply route for a gas running to the output side and operated by a pressure of gas, and alarming by effecting display different from that during an ordinal state by directly exerting a pressure higher than than a given pressure exerting on the emergency cut-off part 15.
