This reactor is provided with: a reaction-side flow passage (210) through which flows a reactant fluid constituting a fluid for reaction; a temperature control unit (heat medium-side flow passage) (220) for heating or cooling the reactant fluid from outside the reaction-side flow passage (210); and a catalyst (140) for accelerating the reaction of the reactant fluid, situated within the reaction-side flow passage (210) in such a way that the surface area of contact with the reactant fluid is greater at the downstream side than at the upstream side within the reaction-side flow passage (210). |
