Disclosed is a method for manufacturing light control particles usable for a light control material comprising: a resin matrix made from a polymeric medium that is cured by irradiating with an energy beam; and a light control suspension comprising: a dispersing medium; and the light control particles that are dispersed in the dispersing medium so as to be in a flowing state, the method comprising the step of granulating after mixing elemental molecular iodine (A), an alkaline earth metal iodide (B), and a heterocyclic compound (C) with each other in a medium, wherein in the step of granulating, reaction is carried out in the presence of methanol in an amount of not less than 50 parts by mass but not more than 110 parts by mass relative to 100 parts by mass of the whole of components (A), (B) and (C). In this way, it is possible to provide a method for manufacturing light control particles wherein the effect of water is decreased in a granulating step of the method in order to yield effectively light control particles having a particle size and shape optimal for light control material and further a good reproducibility is attained.
