To provide an exhaust gas sampling apparatus capable of reducing deterioration of a suction ability due to clogging of a filter for capturing dust in an exhaust gas.
An exhaust gas sampling apparatus 101 in a vacuum refining furnace 20 includes a first suction tube 112 which extends from the inside to the outside of an exhaust pipe 24 for discharging an exhaust gas in the vacuum refining furnace 20, and a filter 111 attached to an end opening 112a of the first suction tube 112 which opens within the exhaust pipe 24. The end opening 112a of the first suction tube 112 opens from an upstream side to a downstream side in an exhaust gas circulation direction within the exhaust pipe 24, and the filter 111 extends from the end opening 112a of the first suction tube 112 from the upstream side to the downstream side in an exhaust gas circulation direction within the exhaust pipe 24.
