1. A laminated body comprising:
a glass substrate; and
a laminated film installed on a surface of the glass substrate, wherein
the laminated film comprises, from a side of the glass substrate,
a first layer comprising silicon nitride;
a second layer comprising silicon; and
a third layer comprising silicon nitride,
a thickness of the first layer is from 5 nm to 30 nm;
a thickness of the second layer is from 3 nm to 40 nm;
a thickness of the third layer is from 5 nm to 60 nm;
a transmittance of visible light incident from the side of the glass substrate is greater than or equal to 10%, and
a surface resistance value measured from a side of the laminated film is greater than 200 Ω/sq,
wherein a ratio of the transmittance of visible light Tv to a reflectance of visible light reflected from a side of the glass substrate Rv, Tv/Rv, is greater than or equal to 0.3 and less than or equal to 2.0.
