Adhesion between a semi-infinite elastic body and a rigid surface with a sinusoidal roughness is solved. The solution is exactly same as that of K. L. Johnson (Int. J. Solids Structures, v.32, p.423 (1995)), although the different method is used for the derivation. Based on the solution, possibility of reversible joining process is considered. Conditions for the complete contact and the partial contact are clearly expressed as the function of the surface roughness, the elastic constant, the work of adhesion, and external pressure. The adhesion stress is expressed as the function of the other parameters. It is suggested that an infinite stress is required to separate the complete contact. The reversible joint is possible if it is designed under the partial contact condition. A critical area contact parameter is found, less than which the reversible joint should be designed.
