Abstract
The laminate includes a multilayer polyimide film having thermoplastic polyimide layers on both sides of a core layer which is a non-thermoplastic polyimide film and a surface layer contacting the thermoplastic polyimide layer on one surface-side of the multilayer polyimide film. The surface layer may be an inorganic layer having a thickness of 1 to 200 nm or a resin layer having a thickness of 0.1 to 5 μm. A single-sided metal-clad laminate is formed by laminating a metal layer on the thermoplastic resin layer on the surface layer non-formed surface of the laminate.
