An object of the invention is to use general-purpose glass, such as soda lime glass containing Na and Ca, as a high-durability glass substrate with an antireflection film. Namely, the object of the invention is to provide a glass substrate which provides an antireflection function to increase the transmission rate of incident light, and inhibit Na or Ca in the glass substrate from diffusing to the surface of the antireflection film in high-temperature high-humidity environment, thereby inhibiting nebula of the antireflection film. The glass substrate (1) provided by the invention is a glass substrate (2) with an anti-reflection film (3), and is characterized in that, the glass substrate (2) contains at least one alkali metal selected from Na and Ca; the anti-reflection film (3) contains SiO2 and has a reflection rate of 1.35-1.50; and a diffusion inhibition film (4) containing 1-12 atom% of P is arranged on the interface of the surface of the glass substrate (2) and the anti-reflection film (3). |
