Provided is a laminated polyimide substrate having various properties secured and / or imparted by effectively suppressing changes over time under severe conditions while ensuring sufficient adhesion between the polyimide film and the metal layer, and a method for producing the same. For the purpose. A polyimide layer, an alkali-treated layer derived from the polyimide layer, and a metal layer are arranged in this order, and are laminated polyimide bases, the alkali-treated layer contains an anionic functional group, and on the metal layer side A laminated polyimide substrate comprising a layered structure comprising a layer containing a catalyst metal and a layer containing a catalyst metal complex and arranged on the polyimide layer side. |
