A device for sampling exhaust gas is provided to increase the temperature of exhaust gas to a measurement temperature rapidly and to extend service life of the sampling device by providing heat uniformly over a device body. A device for sampling exhaust gas includes a body(200), a gas extraction pipe(300), a heater(400), and a distribution pipe(500). The body has a first flange to be attached to a chimney in the front of the body and a cylindrical part(230) in the rear. An inside of the cylindrical part is hollowed and an end of the cylindrical part is opened. The gas extraction pipe is connected to the front of the body so as to be protruded toward the inside of the chimney. A gas extraction hole(310) is formed on a bottom of the gas extraction pipe to extract the exhaust gas and prevents minute dust from flowing into the gas extraction hole. The heater is attached to an outside of the cylindrical part and provides heat for the exhaust gas extracted through the gas extraction pipe. The distribution pipe is inserted into an inside of the cylindrical part and has a second filter(510), a plurality of gas providing holes(540) and a compressed air inflow hole.
