<P>PROBLEM TO BE SOLVED: To prevent a cooling tube from being clogged, even when collected sampling gas contains high-concentration dust. Ž<P>SOLUTION: This gas sampling device is a device installed on a furnace wall of a metallurgical furnace, for sampling furnace gas. When being installed on the furnace wall, the device is constituted by integrating in a body: a water cooling probe 1 whose tip part is positioned over the furnace outside from the furnace wall inner surface; a dust collector 2 connected to the base end side positioned out of the furnace of the water cooling probe 1, for removing coarse particulate dust from sampling gas collected from the tip of the water cooling probe 1; and a cooling device 3 arranged on the downstream side of the dust collector 2, for cooling the sampling gas from which the coarse particulate dust is removed. Since the dust collector is arranged on the upstream side of the cooling device, clogging of the cooling tube is not generated, even when the collected gas contains high-concentration dust.
