An object of the present invention is to provide a laminated polyimide substrate and a method for producing the same, which are capable of effectively suppressing changes over time under excessive conditions while ensuring sufficient adhesion between the polyimide film and the metal layer, and securing and / or imparting various characteristics. A laminated polyimide substrate in which a polyimide layer, an alkali treatment layer derived from the polyimide layer, and a metal layer are arranged in this order, wherein the alkali treatment layer includes an anionic functional group and is disposed on the metal layer side, A laminated polyimide substrate comprising a layered structure of a layer containing a catalyst metal and a layer containing a complex of the catalyst metal disposed on the polyimide layer side is disclosed. |
