To provide glass with a laminated film including a photocatalytic film which prevents the pollution of the surface of a base material such as the glass caused by low molecular siloxane or the like isolated from a silicone-based sealing material for a long period and keeps transparency and has a self-running-off-layer free from deterioration of various characteristics such as the hydrophilicity of the photocatalytic film and a method of manufacturing the same.

In the glass workpiece with the photocatalytic film using the base material with the photocatalytic film as the glass with the photocatalytic film comprising glass with the photocatalytic film and the sealing material, the methylene blue decomposition property of the photocatalytic film is ≥0.08 (Abs) and the quantity of the low molecular siloxane eluted from the sealing material is <100 ppm.
