PROBLEM TO BE SOLVED: To provide a selective permeation membrane type reactor which is high in permeation speed of a selective permeation membrane not only in the vicinity of the gas inlet of a reaction tube colliding with the upstream side in the supply direction of a raw material gas but also in the vicinity of the gas outlet of the reaction tube colliding with the downstream side in the supply direction of the raw material gas and can effectively extract a produced gas to be separated over the entire selective permeation membrane. SOLUTION: This selective permeation membrane type reactor has the cylindrical reaction tube 1 in which one end part is the gas inlet 9 and the other end part is the gas outlet 10, a separation tube 4 which is inserted into the reaction tube 1 and has the selective permeation membrane 5 on the surface, and a catalyst 6 arranged between the reaction tube 1 and the separation tube 4. In the reactor, the distance between the reaction tube 1 and the selective permeation membrane 5 in the inside of the reaction tube 1 is gradually narrowed from the inlet 9 toward the outlet 10.
