1. A peeling device for a resin layer coating a rectangular wire in which an outer side of a metal conductor having a rectangular shape in cross section and having chamfered corners is coated with the resin layer comprising:
a processing blade configured to peel off the resin layer;
a jig configured to hold the rectangular wire; and
a position detector configured to detect a position of a cutting edge of the processing blade with respect to a surface of the metal conductor,
wherein the cutting edge of the processing blade is caused to penetrate into a predetermined thickness position of the resin layer, and the processing blade and the rectangular wire are relatively moved in a longitudinal direction of the rectangular wire without contact of the cutting edge with the metal conductor to perform treatment of peeling off the resin layer, and
wherein the processing blade includes
a pair of upper and lower processing blades disposed to face the upper and lower surface-side coating resin layers of the rectangular wire,
a pair of left and right processing blades disposed, behind the pair of upper and lower processing blades, to face the left and right surface-side coating resin layers of the rectangular wire, and
four chamfered-corner processing blades disposed, behind the pair of left and right processing blades, to face chamfered-corner coating resin layers of the rectangular wire.
