PROBLEM TO BE SOLVED: To provide a joint member capable of easily forming a joint-like pattern without forming a seam on a surface of a concrete structure. SOLUTION: This joint member is provided with a joint part body 1 for forming a joint-like part, and a sandwiching part 2 sandwiched between mutual concrete forms, and supporting the joint part body 1 on an inside surface of the concrete forms. A concrete material is placed in a state of supporting the joint part body 1 by sandwiching the sandwiching part 2 in a form seam part of a concrete form inside surface. When separating and removing the concrete forms after curing and hardening, the joint part body 1 remains in a surface part of the concrete structure in an embedded state, and the joint-like pattern is formed in the part. Thus, the seam is not transferred to the surface of the concrete structure so that a beautiful appearance is improved, and complicated postprocessing work for recovering the seam part by chipping and plasterer work is obviated so that a construction period can be shortened, and a cost can be reduced.
