摘要

[Problem] To provide an aliphatic polycarbonate, an oxide precursor, and an oxide layer with which stringiness can be controlled when forming, using a printing method, a thin film that can be employed in an electronic device or a semiconductor element. [Solution] This oxide precursor is obtained by dispersing a metal compound, which forms a metal oxide when oxidized, in a solution containing a binder that comprises aliphatic polycarbonates (and may also contain unavoidable impurities), wherein the ratio of aliphatic polycarbonate having a molecular weight of 6,000-400,000, inclusive, to all the aliphatic polycarbonates is 80 mass% or more. As a result, as shown in FIG. 1, a good pattern that can be used in the production of a semiconductor element can be formed.
