PROBLEM TO BE SOLVED: To provide a temperature-sensitive light-shielding material that is designed to shield light at high temperatures and allows light to transmit at low temperatures. SOLUTION: The temperature-sensitive light-shielding material has a synthetic resin layer where a polymer solution exhibiting LCST behavior is dispersed. Preferably, a gelled resin crosslinked by ultraviolet having an ultraviolet crosslinking function is used for the synthetic resin, including, for example, a urethane acrylate, an epoxy acrylate, an ester acrylate, etc. For the polymer solution exhibiting LCST behavior, an aqueous solution of an acrylamide derivative or an aqueous solution of a saccharide derivative is preferably used.
