Abstract: An optical member includes a transparent substrate containing at least one substance selected from glass, a glass ceramic, silicon, and sapphire, and having an infrared high-transmittance region in which an optical transmittance is 78% or more in a wavelength band of 700 nm to 1800 nm; and an optical interference film disposed on a main surface of the transparent substrate corresponding to the infrared high-transmittance region, wherein a transmittance of light, of the optical member, of at least one wavelength λ3 in the wavelength band of 700 nm to 1800 nm in a region of the optical member corresponding to the infrared high-transmittance region of the transparent substrate has a minimum value of 86.5% or more and has a difference between the minimum value and a maximum value of 9% or less in a range where an incidence angle is from 0 degrees to 60 degrees.

Abstract: To provide a cover glass for a solar cell module which can sufficiently maintain the power generation efficiency of a solar cell module, even when a design is imparted to the entire surface of the cover glass so as to make solar cells be invisible from the outside, and a solar cell module.
To provide a cover glass 14 to be bonded on light-receiving surfaces 16A and 16B of solar cells 16 via an encapsulant material 18, which has a visible transmittance of from 0% to 60% and an average infrared transmittance of from 20% to 100%, which is a value calculated by simply averaging transmittances at 5 nm intervals in an infrared region at a wavelength of from 780 nm to 1,500 nm.
