In the present invention, the insulating layer of the laminate comprising the first inorganic layer-insulating layer-second inorganic layer, or the inorganic layer-insulating layer is a resin layer of two or more layers of the core insulating layer and the adhesive insulating layer. It is to provide the resin laminated body which has the adhesive insulating layer which can perform suitable etching, is suitable for the etching by a wet method, and is excellent in adhesiveness, At least 1 layer which forms an insulating layer is represented by General formula (1). It is a polyimide resin having a repeating unit shown, and also has a glass transition point of 150 ~ 360 ℃, the dissolution rate in the basic solution is larger than 3㎛ / min, preferably larger than 5㎛ / minute, most preferred Is characterized in that the polyimide resin is larger than 8 µm / min.n n n n Laminates, Uses |
