Abstract: The present invention relates to a flexible and transparent polyimide laminate and manufacturing method thereof. The flexible and transparent polyimide laminate comprises a conductive layer, an adhesive layer and a polyimide substrate. The conductive layer includes a plurality of metal nanowires, and is attached on the polyimide substrate by the adhesive layer. The adhesive layer is an insoluble polyimide film and is polymerized by aromatic dianhydride and one of the following monomer: alicyclic diamines, fluorine-containing diamines, and the combination thereof.
