An exhaust gas measuring bag includes a gas connection part (1) which is connected to a constant volume sampling passage (Z5) flowing measurement gas therethrough for analyzing various components included in exhaust gas (G) of the automobile etc. therethrough and has an internal passage flowing the gas taken from the constant volume sampling passage (Z5) therethrough; a pipe (2) which is connected to an internal passage of the gas connection part (1) and on which a plurality of gas inlet/outlet holes (21) for ejecting the gas are formed; a bag body (3) which is deformable and has an internal space (30) for storing at least the connection side of the gas connection part (1) to the pipe (2) and the whole of the pipe (2) therein and encloses gas ejected from the gas inlet/outlet holes (21) into the internal space (30) therein; a gas exhaust port (4) which is provided at the gas connection part (1) and exhausts the gas enclosed in the internal space (30) to the constant volume sampling passage (Z5); and a check valve (5) which is disposed on an exhaust passage (13), opens the exhaust passage (13) at the time of exhaust of the gas, thereby allowing the gas to pass and closes the exhaust passage (13) at the time of non-exhaust of the gas, thereby preventing passage of the gas.
