PROBLEM TO BE SOLVED: To more enhance precision than before with respect to the sampling result of a surface discharge gas without obstructing the discharge of the surface discharge gas. SOLUTION: This sampling device of the surface discharge gas has a storage container (sampling bag 34) equipped with the holding member (bag fixing part 48) closely brought into contact with an entrance and exit port part so as to prevent a gas from flowing in and flowing out of a container in a state that at least a part of the surface of matter is covered with the container or introduced into the container, a pressure sensor 46 for detecting the close contact pressure due to the holding member, a pressure control means (programmable controller 12) for controlling the close contact pressure, a gas washing means (12) for passing a clean gas through the storage container to expel a residual gas to wash the storage container, a gas storage means (12) for storing the surface discharge gas discharged from a surface during a predetermined period in the storage container after the residual gas is expelled and a gas derivation means (12) for deriving the surface discharge gas to a preserving container (preserving bag 52) from the storage container after a predetermined period is elapsed.
