PROBLEM TO BE SOLVED: To provide a connection structure of PC beam members, which does not require much time and labor when produced and constructed, and contributes to cost reduction. SOLUTION: A pair of the PC beam members 20, 30 are full PC members. One of the PC beam members 20 is formed of: beam main reinforcements 21, 22 which are embedded in the PC beam member 20 and extend to a connection end; a PC fitting portion 40 which is protruded from a connection end face 20A of the one PC beam member 20 in a beam axial direction; and overlapping reinforcements 41, 42 which are embedded in the PC fitting portion 40 and extend in the beam axial direction. The other PC beam member 30 is formed of: beam main reinforcements 31, 32 which are embedded in the PC beam member 30 and extend to a connection end face 30A; and a notched portion 34 formed in a connection end of the PC beam member 30 and opened in the connection end face 30A. Herein the PC fitting portion 40 is fitted into the notched portion 34 formed in the other PC beam member 30, and the overlapping reinforcements 41, 42 are arranged astride joint portions of the beam main reinforcements 21, 22, 31, 32 of the PC beam members 20, 30, respectively, followed by pouring grout in a gap between the PC fitting portion 40 and the notched portion 34 formed in the PC beam member 30.
