PROBLEM TO BE SOLVED: To provide a premixed gas supply testing device capable of reducing waiting time and improving test efficiency by reducing abrupt expansion of volume of premixed gas in a combustion vessel when supplying gas for stabilizing temperature and pressure of the premixed gas, and capable of stabilizing fuel concentration in the premixed gas immediately after starting to supply gas and temperature of the premixed gas. SOLUTION: In the device for introducing the premixed gas into the combustion vessel 1 for performing combustion-related tests, a gas supply bypass exhaust line 14 including a gas supply bypass exhaust valve 13 is branched from a premixed gas supply line 6 between a gas heater 4 and a gas supply valve 5 for connecting to an exhaust line 9 at a downstream of a vacuum pump 8, an exhaust auxiliary valve 15 is provided in the exhaust line 9 between an exhaust valve 7 and the vacuum pump 8, and a pressure control line 17 including a pressure control valve 16 is branched from the exhaust line 9 between the exhaust valve 7 and an exhaust auxiliary valve 15 for connecting to the exhaust line 9 at a downstream side of the vacuum pump 8.
