To provide the joining member and the creation method of the joining member that can improve a holding action and wet-spreading property of an adhesive agent, and that can improve and reduce variation in adhesive strength at a fitting part.SOLUTION: The joining member is formed in which a cylindrical surface form outer peripheral surface and a cylindrical surface form inner peripheral surface are joined via an adhesive agent at a fitting part therebetween. At least one of adhesive surfaces of the cylindrical surface form outer peripheral surface and the cylindrical surface form inner peripheral surface is intermittently provided with concave grooves and periodic grating-shaped convexoconcave structures having a periodic interval smaller than a groove width of the concave groove. The cylindrical surface form outer peripheral surface and the cylindrical surface form inner peripheral surface are bonded to each other at the fitting part between the cylindrical surface form outer peripheral surface and the cylindrical surface form inner peripheral surface with the adhesive agent interposed therebetween.SELECTED DRAWING: Figure 1
