Document Type and Number:
WIPO Patent Application WO/2018/074004
Kind Code:
A1
Abstract:
A production method for an insulated electric wire, the production method including: a step for preparing a linearly-shaped conductor; a step for forming an insulating coating film that comprises an insulator and has pores on the inside thereof over the outer circumferential surface of the conductor so as to obtain an insulated electric wire that includes the conductor and the insulating coating film that coats the conductor; and a step for detecting the electrostatic capacity of the insulated electric wire and inspecting the formation state of the insulating coating film on the basis of the relationship between said electrostatic capacity and the porosity of the insulating coating film.
