An object is to provide a laminated polyimide substrate, and a method for the production thereof, in which various properties are ensured and/or provided by effectively controlling changes over time under stringent conditions, while ensuring sufficient adhesion between a polyimide film and metal layer. A laminated polyimide substrate comprising a polyimide layer, an alkali-treated layer derived from the polyimide layer, and a metal layer, arranged in that order, wherein the alkali-treated layer contains an anionic functional group, and is a laminated structure having a layer containing a metal catalyst arranged on the metal layer side and a layer containing a complex of the metal catalyst arranged on the polyimide layer side.
