Provided is a frame structure which allow PC members to be assembled in an efficient manner. First blind holes 26 are formed in a first PC beam 11 so as to open out at longitudinal end surfaces thereof, and first through holes 31 are formed in a pair of PC columns 10 so as to open out opposite to the respective first blind holes 26. The first PC beam 11 is rigidly connected to each PC column 10 via a first rebar 32 positioned in each first through hole 31 and inserted in the corresponding first blind hole 26 to be connected to the corresponding first main beam rebar 24 via a first overlap joint 33, and grout filled around the first rebar 32 in the first through hole 31.
