Abstract: An object is to provide an optical glass with a near-infrared absorbing function that maintains constant and high transmittance in a visible light range and also has excellent oblique incidence characteristics as well as excellent durability, heat resistance, and weather resistance, and to provide a near-infrared cut filter, a glass element for press molding, an optical element blank, and an optical element including the same. Provided is an optical glass including a glass composition as a base containing at least Yb2O3 and B2O3 as essential components, the optical glass characterized in that a content of Yb2O3 is 5% to 60% by mass, a content of B2O3 is 10% to 50% by mass, and when a thickness of the optical glass is 2.5 mm, average transmittance in a wavelength range of 925 to 955 nm is 0% to 70%, and average transmittance in a wavelength range of 965 to 985 nm is 0% to 50%.
