An exhaust gas sampling device is provided. An exhaust gas sampling tube for sampling part of the exhaust gas is connected to an exhaust tube in which the exhaust from a source of the exhaust gas flows, and a downstream side of the exhaust gas sampling tube is connected to a dilution tunnel. The device further includes a temperature control mechanism. A temperature of the exhaust gas sampling tube is controlled with the temperature control mechanism based on a temperature of the exhaust gas flowing in the exhaust tube.
