PROBLEM TO BE SOLVED: To provide a method of forming a conductor pattern that improves insulation reliability between conductor patterns by preventing residues from remaining between the conductor patterns, and prevents a surface of an insulating substrate from decreasing in reflection factor. SOLUTION: The conductor pattern 3 is formed through the steps of: forming a conductor film 2 on the surface of the insulating substrate 1; performing etching processing on the conductor film 2 to remove part of the conductor pattern 2 in a prescribed pattern; and carrying out sand blast processing to remove residues 2a of the conductor film 2 remaining on the surface of the insulating substrate 1 at the part where the conductor film 2 is removed.
