PROBLEM TO BE SOLVED: To solve the problem of not sufficiently exhibiting its yield strength by using a reinforcement as a main reinforcement without using an ordinary PC steel material for introducing prestress, due to requiring much labor for securing a work space for tension work by lengthening of a construction period due to causing a danger in field work, in a conventional construction method for introducing the prestress into a column/beam joint part. SOLUTION: In this column/beam joint structure, a joint member is formed by integrally forming a joint part of a column and a beam and an end part of the beam in a factory; a column main reinforcement and a beam main reinforcement 3 are arranged in a required position of the joint member; its end part projects from upper-lower end surfaces of the joint part and a connecting end surface of the beam; and the prestress is imparted to the integrated joining member 1 by the beam main reinforcement 3.
