Abstract

The adhesive film includes a film-like adhesive layer, a light release separator and a heavy release separator that are laminated on either side of the adhesive layer, and a carrier film further laminated on the heavy release separator. The outer edges of the light release separator and the carrier film forming the outer layer extend outward beyond the outer edge of the adhesive layer and the heavy release separator forming the inner layer. The outer edge sections of the adhesive layer are thereby protected. The outer edge section of the carrier film is gripped and released first, after which the outer edge section of the light release separator is gripped and released, and finally the heavy release separator is released, thereby allowing each separator and the carrier film to be reliably and easily released in the prescribed order.
