In a step of performing dicing by sticking a protective tape for protecting a wafer surface, in order to obtain a dicing method which ensures that there is no paste residue on a chip side face and that the protective tape is prevented from peeling from the wafer during the dicing and which is excellent in productivity, in a step of performing dicing by sticking a surface protective adhesive tape having an energy ray-curable adhesive layer on one surface of a substrate, thereby performing surface protection for the surface of the semiconductor wafer where an integrated circuit is to be formed, the energy ray-curable adhesive layer is cured by radiating energy rays beforehand to an inner circumferential portion of the wafer, and dicing is performed, with the energy ray-curable adhesive layer kept in an uncured condition by ensuring that energy rays are not radiated to an outer peripheral portion.
