To provide a production method of an insulated wire and the insulated wire. The water stop treatment is performed by: a partial exposure step in which an insulated electric wire (1) having a conductor (2) formed by stranding a plurality of wire materials composed of a conductive material and an insulating cover (3) covering the outer periphery of the conductor (2), an exposed part (10) obtained by removing the insulating cover (3) from the outer periphery of the conductor (2) and a coating part (20) in a state where the insulating cover (3) covers the outer periphery of the conductor (2) are arranged adjacent to each other in the long axis direction of the insulated wire (1); a step of modulating the density of expanding a space between the element wires in the exposed part 10 while heightening the density of the conductive material per unit length in the exposed part 10, and a step of filling of filling the sealant 5 made of the insulating material in a space between element wires in the exposed part 10. 本发明
