Abstract
Abstract A sticking material for preventing resticking having an adhesive layer, a second layer laminated on one main surface of the adhesive layer, a peeling agent layer laminated on the second layer and a first layer laminated on the peeling agent layer. The following equation, a<b is satisfied, wherein the force required to separate the first layer from the second layer at the peeling agent layer is denoted as a, and the adhesive force of the adhesive layer with the surface of the second layer is represented by b. Since the second and first layers are adhered temporarily via the peeling agent layer, the first layer once separated from the second layer, cannot be restuck.
