Abstract
A method for producing an insulated electric wire includes a step of preparing a conductor having a linear shape; a step of forming an insulating coating so as to cover a surface on an outer peripheral side of the conductor to obtain an insulated electric wire that includes the conductor and the insulating coating covering the conductor; and a step of measuring a first electrostatic capacity between the insulated electric wire and a first electrode disposed outside in a radial direction of the insulated electric wire so as to face an outer peripheral surface of the insulated electric wire while transporting the insulated electric wire in a longitudinal direction of the conductor, and inspecting a formation state of the insulating coating, the formation state including a formation state of a defective portion in the insulating coating, on the basis of a change in the first electrostatic capacity.
