PROBLEM TO BE SOLVED: To provide an easily-manufacturable decorative joint material for an inducing joint portion of concrete, which makes the number of components smaller by a simple structure, which can ensure sufficient water sealability, and which dispenses with repair. SOLUTION: The decorative joint material 20, which is provided on the surface of the inducing joint portion of the concrete, is used concurrently with inducing joint materials 12 and 12A for inducing the occurrence of cracking, associated with the shrinkage of the concrete, in a specific location. The decorative joint material 20 comprises: a surface adhesion portion 21 which is provided along the inside of the surface of the inducing joint portion of a concrete form so as to adhere to a form surface; an internal protrusion 22 which is integrated with the surface adhesion portion 21 so as to protrude into the concrete; and a water-sealing anchoring portion 23 which is integrated with both the sides of the surface adhesion portion 21, so as to water-seal a section between the concrete and it. The surface adhesion portion 21 adheres to an inner surface of the form, so that the internal protrusion 22 integrated with the surface adhesion portion 21, and the water-cutting off anchoring portions 23 on both the sides can water-seal a section between the concrete and each of them.
