To provide a glass structure with which it is possible to suppress a perspective distortion in the vicinity of a boundary between a light-shielding treated part and a translucent part and form an electro-thermal film and a bus bar easily at low cost, and with which the degree of freedom in designing wiring lead-outs from the bus bar is high.SOLUTION: Provided is a glass structure (1) comprising a light shielding treated glass plate 10 having an optical device fitting region (OP), a translucent part (TP) located inside of the optical device fitting region (OP), which incident light from the outside to an optical device and/or emitted light from the optical device passes through, and a light-shielding treated part (BP) enclosing at least a portion of the translucent part (TP); and a translucent tabular member (31) thinner than the light-shielding treated glass plate (10), which is attached to the fitting surface of the optical device of the light-shielding treated glass plate (10) and covers a part of the translucent part (TP) and the light-shielding treated part (BP), with an electro-thermal film (32) and a pair of bus bards (41, 42) for feeding electricity to the electro-thermal film (32) formed on top of the translucent tabular member (31).SELECTED DRAWING: Figure 1
【課題】遮光加工部と透光部との境界近傍における透視歪を抑制でき、電熱膜およびバスバーを簡易に低コストに形成でき、バスバーからの配線引出の設計自由度が高いガラス構造体の提供。【解決手段】光学装置取付領域(OP)と、光学装置取付領域(OP)内に位置し、外部から光学装置への入射光および/または光学装置からの出射光が通る透光部(TP)と、透光部(TP)の少なくとも一部を囲む遮光加工部(BP)とを有する遮光加工ガラス板10と、遮光加工ガラス板(10)の光学装置の取付面上に透光部(TP)および遮光加工部(BP)の一部を覆って取り付けられた、遮光加工ガラス板(10)よりも薄い透光性板状部材(31)とを有し、透光性板状部材(31)上に、電熱膜(32)と、電熱膜(32)に給電するための一対のバスバー(41、42)とが形成された、ガラス構造体(1)。【選択図】図1
