To provide an ultraviolet shielding glass excellent in ultraviolet shielding property and external appearance.SOLUTION: An ultraviolet shielding glass comprises a glass plate, and an ultraviolet shielding film disposed on a principal surface of the glass plate. The ultraviolet shielding glass is such that: the ultraviolet shielding film is a continuous film having no sudden change portion in the film thickness; the ultraviolet shielding film has in a plan view, a peripheral region as a region of a width of 1 mm to the inside from an outer peripheral edge of the ultraviolet shielding film, an intermediate region as a region of a width of 59 mm to the inside from an inner peripheral edge of the peripheral region, and a center region surrounded by the intermediate region; a cross-sectional shape of the ultraviolet shielding film in the peripheral region has an upward projecting curve; a cross-sectional shape of the ultraviolet shielding film in the intermediate region has an upward projecting curve; a maximum film thickness of the ultraviolet shielding film in the center region is 1 μm-10 μm; and when the ultraviolet shielding glass is mounted on a vehicle body opening, the peripheral region includes a peripheral region part along an upper side of the ultraviolet shielding glass, and in the peripheral region part, a maximum film thickness of the ultraviolet shielding film is 0.4 μm-1.0 μm.SELECTED DRAWING: None
【課題】紫外線遮蔽性及び外観に優れる紫外線遮蔽ガラスを提供する。【解決手段】ガラス板と、ガラス板の主面に設けられた紫外線遮蔽膜と、を備える、紫外線遮蔽ガラスであって、紫外線遮蔽膜はその膜厚に急変部がない連続膜であり、紫外線遮蔽膜は、平面視で、紫外線遮蔽膜の外周縁から内側へ1mmの幅の領域である周縁領域と、周縁領域の内周縁から内側へ59mmの幅の領域である中間領域と、中間領域に囲まれた中央領域とを有し、周縁領域における紫外線遮蔽膜の断面形状が上に凸の曲線を有し、中間領域における紫外線遮蔽膜の断面形状が上に凸の曲線を有し、中央領域における紫外線遮蔽膜の最大膜厚が1μm~10μmであり、紫外線遮蔽ガラスが車体開口部に取り付けられた場合、周縁領域が紫外線遮蔽ガラスの上辺に沿った周縁領域部分を含み、周辺領域部分において、紫外線遮蔽膜の最大膜厚が0.4μm~1.0μmである、紫外線遮蔽ガラス。【選択図】なし
