Redundant wiring apparatus and a method of making the same

A redundant wiring apparatus comprising:

• an insulation substrate;
• an insulation layer formed on said insulation substrate;
• a plurality of wiring groups, each group including a first wire formed between said insulation substrate and said insulation layer and a second wire disposed along said first wire and formed on said insulation layer;
• and
• first and second connectors to electrically connect said first wire with said second wire at both end portions of each of said wiring groups, respectively;
• wherein at least one of said first and second wires includes first and second repairing portions provided between said first and second connectors of each of said wiring groups;
• wherein said first wire is not overlapped with said second wire at said first and second repairing portions;
• and
• wherein, when said second wires in neighboring ones of said wiring groups are short-circuited, one of said short-circuited second wires is cut off at the first and second repairing portions thereof.
