To provide a vehicle window glass with an optical device capable of: eliminating distortion derived from an irregularity generated on a boundary between a shield layer of the vehicle window glass and a region inside the shield layer; widening a range usable by an optical element; and being easily manufactured.SOLUTION: A tabular translucent member 5 is adhered to a vehicle inner side of a light transmission region 20 of a vehicle window glass 2 via a light transmission adhesive. A total thickness of thicknesses of the tabular translucent member 5 and the light transmission adhesive 4 is 50% or less of thickness of the vehicle window glass 2. A portion having a length of 2 mm or less, of a gap between an outer edge of the tabular translucent member 5 and an inner edge of the shield layer 6 accounts for 40% or more with respect to an entire outer periphery of the tabular translucent member 5.SELECTED DRAWING: Figure 2
【課題】車両用窓ガラスの遮蔽層とその内側の領域との境界で生じる凹凸に起因する歪みを解消し、光学素子で利用できる範囲を広くし、車両用窓ガラスを容易に製造できる光学装置付き車両用窓ガラスを提供すること。【解決手段】車両用窓ガラス2の光透過領域20の車内側に板状透光性部材5が光透過接着剤で貼り付けられ、板状透光性部材5と光透過接着剤4との厚さの合計が車両用窓ガラス2の厚さの50%以下であり、板状透光性部材5の外縁と遮蔽層6の内縁との隙間のうち2mm以内の部分が板状透光性部材5の全外周に対して40%以上とした。【選択図】図2
