  The present invention increases the reflectivity for reflected heat radiant heat from the heat source such as the sun or heating or the surrounding material by particles made of a material having high heat reflectivity and low heat absorption and heat conductivity on one or both sides. Further, the present invention relates to a flexible thermal insulator having permanent thermal insulation of a thin film by mirror film insulation, and to a flexible thermal insulator in which this is applied to a film or a roll screen.

Conventionally, in order to shield radiant heat from sunlight from the window glass, the following methods have been used in various directions, such as a glass heat reflective or heat absorbing film, or a heat absorbing property. It uses glass such as metal film coating, glass with metal vapor deposition film, glass laminated with heat-absorbing film, and multilayer glass with glass with metal vapor deposition film. In addition, there is a window in which a light shielding curtain such as a dark curtain, a roll screen, a sheet on which a metal-deposited film is bonded, a heat shielding roll screen using a cloth coated with metal particles, a blind, and the like are installed inside the window.
