Abstract

An object of the invention is to provide an oxide thin film which exhibits a widegap or transparency and p-type conductivity although it has heretofore been very difficult to form. The oxide thin film formed on a substrate contains copper oxide and strontium oxide as a main component and exhibits p-type conductivity at a bandgap of at least 2 eV.
