The invention provides a process for producing an adhesive patch, which includes a step of preparing a pressure-sensitive adhesive sheet including a backing, a pressure-sensitive adhesive layer formed on at least one side of the backing, and a release liner disposed on the pressure-sensitive adhesive layer； and a step of punching an adhesive patch including a backing, a pressure-sensitive adhesive layer formed on at least one side of the backing, and a release liner disposed on the pressure- sensitive adhesive layer out of the pressure-sensitive adhesive sheet with a protrudent push cutter blade, in which, at at least an edge part of the protrudent push cutter blade, a cross-sectional shape of the protrudent push cutter blade, which is in a direction perpendicular to the direction in which the protrudent push cutter blade extends, has an angle .alpha. and an angle b, in which the angle .alpha. is larger than the angle b. The angle .alpha. and angle b in the sectional shape have the meanings described in the specification.
