In carrying out the reaction as described above, the reagent (30a) is passed in such a manner that the periphery of the gas/liquid interface at the front end of the reagent moves forward and backward along the wall face of the reaction channel (10). After the completion of the reaction between the reagent (30a) and the reactant, another reagent (30b), which is to be reacted with the reactant capable of reacting with the reagent that is carried on the reaction channel, is passed into the reaction channel (10) while providing a gas in the front edge side thereof.
