PROBLEM TO BE SOLVED: To hardly generate air bubbles in hardened grout, when the grout is efficiently injected into each reinforcement inserting hole after the insertion of the reinforcement. SOLUTION: In this grouting method, the grout G is injected in a state in which reinforcements 14 are inserted into the plurality of reinforcement inserting holes of a precast concrete member A preinstalled in such a manner that the plurality of reinforcement inserting holes 1 are juxtaposed in upper and lower positions, respectively. Communication passages 5, which make the plurality of reinforcement inserting holes communicate with one another in order from the lower reinforcement inserting holes to the upper reinforcement inserting holes, are provided. A grouting passage 7 communicates with the lowermost reinforcement inserting hole, and an air vent passage 9 communicates with the uppermost reinforcement inserting hole, so that the grout can be injected from the grouting passage.
