<P>PROBLEM TO BE SOLVED: To provide a copper oxide paste capable of precisely forming a metal copper layer having high definition and low resistance, and a method for producing a metal copper layer using the copper oxide paste. <P>SOLUTION: The copper oxide paste is configured to contain: a copper oxide particle group in which the average of major-axis lengths is equal to or longer than 100 nm and shorter than 1700 nm, and a ratio of the average of the major-axis lengths to the average of minor-axis lengths is 1.2 to 20 inclusive; and a dispersion medium. The copper oxide paste is applied onto a support and is subjected to a conductor forming treatment, thereby producing a metal copper layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
