Document Type and Number:
Japanese Patent JP5652135
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method in which a good quality insulated wire can be stably manufactured by preventing cuttings (die drool) from occurring at the tip of a molding die during extrusion coating of an insulation coating layer and securing long-term durability of the molding die.SOLUTION: The manufacturing method of the insulated wire related to the present invention is the manufacturing method of the insulated wire in which a conductor and resin composition are inserted into the molding die and the extrusion coating of the insulation coating layer is performed to the outer periphery of the conductor. The molding die is equipped with an amorphous carbon coating film on a surface in contact with at least the resin composition. The amorphous carbon coating film contains nitrogen, and nitrogen is bonded to carbon constituting the amorphous carbon coating film.
