Abstract
A laminate by using a paste or solution containing aliphatic polycarbonates having an etching mask function is provided. A method of producing a laminate of the present invention includes a pattern forming step of forming a patternof a first oxide precursor layer in which a compound of metal to be oxidized into a metal oxide is dispersed in a solution containing a binder (possibly including inevitable impurities) made of aliphatic polycarbonates on an oxide layeror on the second oxide precursor layer to be oxidized into the oxide layeran etching step of, after the pattern forming step, etching the oxide layeror the second oxide precursor layer that is not protected by the patternand a heating step of, after the etching step, heating the oxide layeror the second oxide precursor layer, and the first oxide precursor layer to a temperature at which the binder is decomposed or higher.
