PROBLEM TO BE SOLVED: To facilitate replacement or repair of a heating part fixed to an outer circumferential surface of an inner cylinder into which produced gas is introduced. ! SOLUTION: There is provided a gas sampling probe 1 for collecting produced gas that is produced in a gas-production furnace. The gas sampling probe 1 includes: a gas cooling pipe 1a into which produced gas in the gas-production furnace is introduced; an external cylinder 1c that is located outside the gas cooling pipe 1a and has a cooling layer 1l to cool the produced gas provided between the external cylinder 1c and the gas cooling pipe 1a; a heater 1b for heating that is fixed to an outer circumferential surface of the gas cooling pipe 1a and heats the produced gas flowing through the gas cooling pipe 1a; and a mechanism for attachment and removal 15 that allows the gas cooling pipe 1a to be attached to or removed from the external cylinder 1c. !
