Abstract

See full text

The object of the invention is to obtain a solar radiation shielding member that has a good visible light transmittance and shows no redness when viewed from the front and when obliquely viewed, without impairing the solar radiation transmittance. A solar radiation shielding member, wherein a first dielectric film, a first metal film, a second dielectric film, a second metal film, a third dielectric film, a third metal film, and a fourth dielectric film are stacked on a transparent substrate; the first dielectric film comprises at least two dielectric layers containing a layer having a refractive index of 2.4 or greater, and the first dielectric film as a whole has a refractive index in a range of 1.8-2.0; the second dielectric film has an optical film thickness of 165-201 nm; the third dielectric film has an optical film thickness of 147-182 nm; the fourth dielectric film has an optical film thickness of 75-120 nm; a geometric film thickness of the first metal film, the second metal film, and the third metal film is 30-40 nm in total; a geometric film thickness of the second metal film is in a range of 1.01-1.55 relative to a geometric film thickness of each of the first metal film and the third metal film.
