PROBLEM TO BE SOLVED: To provide a method for manufacturing a peeling film with high manufacturing yield, capable of reducing manufacturing cost of the peeling film, and capable of achieving the low-price and high-quality peeling film having smoothness, excellent releasability, and mechanical strength.SOLUTION: On a surface of a wide film 20b which is to be a base material film after cutting, a plurality of trains of polymer layers 22 are continuously formed along the longitudinal direction of the wide film 20b at predetermined intervals. A not-forming part 24b, which is not formed with the polymer layers 22 continuously provided on the surface of the wide film 20b along the longitudinal direction, is cut along the longitudinal direction to form a plurality of the peeling films 25 each of which has the not-forming parts 24 on the both sides. The polymer layer 22 has a layer including cured material of a (meth)acrylate component and a film including a silicone polymer component which covers a part of a surface on the opposite side of the base material film side of the layer. The silicone polymer component is a polymer of modified silicone oil modified by a (meth)acryloyl group and/or a vinyl group. |
