The present invention provides a glass sheet having a good property of blocking transmission of ultraviolet light, having a low to moderate visible transmittance, being relatively thin, being capable of substantially blocking transmission of solar ultraviolet light, and also having a good solar shielding property. The glass sheet of the present invention has a thickness of 1 to 5 mm, a Tuv 380 of 1.5% or less, a Tuv 400 of 2.5% or less, a visible transmittance (YA) of 5 to 40%, and a solar transmittance (TG) of 5 to 45%, and is formed from a glass composition, wherein the glass composition includes: 1.0 to 5.0 wt% T-Fe 2 O 3 ; 1.0 to 5.0 wt% TiO 2 ; and 50 to 600 wt. ppm CoO as coloring components in addition to predetermined base composition, a FeO ratio is 5 to 40%, and the sum of T-Fe 2 O 3 multiplied by 2 and TiO 2 is 7.0% or more.
