Layered body

A layered body comprises a polyimide film tightly adhered onto a glass substrate or a silicon substrate, and a metal film or an oxide semiconductor film further layered over the polyimide film. The thickness of the metal film or the oxide semiconductor film is 1 to 400 nm, and the moisture content of the polyimide film is 1000 to 35000 ppm by mass. 一种层叠体，其中，聚酰亚胺薄膜密合于玻璃基板或硅基板上，且在前述聚酰亚胺薄膜上还层叠有金属膜或氧化物半导体膜，前述的金属膜或氧化物半导体膜的厚度为1～400nm，前述聚酰亚胺薄膜的水分含有率为1,000～35,000质量ppm。
