Disclosed is a method for producing a light-modulating film in which a light-modulating layer is sandwiched between two transparent resin substrates, the light-modulating layer being formed by use of a light-modulating material containing: a polymeric medium for forming a resin matrix; and a light-modulating suspension, the method comprising the following steps. Using this method, a light-modulating film can be obtained which has a wholly uniform external appearance and an excellent adhesiveness between its light-modulating layer and transparent resin substrate. the step (a) of applying the light-modulating material to one (a first transparent resin substrate) of the transparent resin substrates; the step (b) of bonding the other transparent resin substrate (a second transparent resin substrate) onto the light-modulating material applied to the first transparent resin substrate; and the step (c) of irradiating the light-modulating material sandwiched between the first transparent resin substrate and the second transparent resin substrate with an energy ray to cure the polymeric medium for forming the resin matrix contained in the light-modulating material, thereby forming the light-modulating layer to yield the light-modulating film.
