Abstract
A light modulation film () includes a light modulation layer () whose state is reversibly changed between a transparent state by hydrogenation and a reflective state by dehydrogenation, and a catalyst layer () that promotes hydrogenation and dehydrogenation in the light modulation layer, in this order on a polymer film substrate (). light modulation layer () includes a light modulation region () having a thickness of 10 nm or more on a catalyst layer ()-side, and an oxidized region () on a polymer film substrate ()-side.
