ABSTRACT OF THE DISCLOSURE A sticking material for preventing resticking comprises an adhesive layer, a second layer laminated on one main surface of the adhesive layer r a peeling agent layer laminated on the second layer and a first layer laminated on the peeling agent layer by coating with a resin. The rela- tive adhesiveness of the various layers is satisfied by the equation: a < b wherein a represents the force required to separate the first layer from the second layer through the intermediary of the peeling agent layer, and b represents the adhesive power of the adhesive layer to a material being sealed. Since the second and first layers are adhered temporarily via the peeling agent layer in a condition whereby resticking is impossible, the first layer once being separated from the second layer can not be readhered.
