To provide a production method which can realize easy production of an antiglare film an antiglare film 10 is produced by performing planar scanning with a laser light on a surface of the antiglare film, wherein the planar scanning comprises: a main-scanning in X direction; and a sub-scanning in Y direction; and controlling an output of the laser light when the main scanning is performed, so as to form the irregular surface upon irradiation with the laser light. In this production method, a beam diameter of the laser light is changed randomly at each irradiation portion of the laser light (in FIGS. 1A-1B, each lattice point of the lattice 14), whereby the output of laser light is controlled.
