It is an object of the present invention to provide a method of reforming an interlayer film for heat-insulating laminated glass by which an interlayer film for heat-insulating laminated glass capable of exhibiting an excellent optical property may be obtained even if heat-insulating fine particles covered with an inert substance are used, an interlayer film for heat-insulating laminated glass, and laminated glass. The present invention is a method of reforming an interlayer film for heat-insulating laminated glass, wherein a high energy ray comprising an electromagnetic wave having energy of 3.0 eV or more is irradiated to an interlayer film for heat-insulating laminated glass comprising a heat-insulating fine particle covered with an inert substance, a matrix resin, and a liquid plasticizer, to improve transmittance of visible light having a wavelength of 380 to 780 nm, and also to reduce transmittance of a near-infrared radiation having a wavelength of 780 to 2100 nm, wherein a surface of the heat-insulating fine particle is inactivated by protecting the surface of the heat-insulating fine particle with an amorphous (noncrystalline) metal oxide. |
