摘要

A p-type oxide which is amorphous and is represented by the following compositional formula: xAO.yCu₂O where x denotes a proportion by mole of AO and y denotes a proportion by mole of Cu₂O and x and y satisfy the following expressions: 0≤x100 and x+y=100, and A is any one of Mg, Ca, Sr and Ba, or a mixture containing at least one selected from the group consisting of Mg, Ca, Sr and Ba.
