Claim 9:
10. A method for producing the insulated electric wire according to claim 1, the insulated electric wire including the conductor in which the plurality of elemental wires made of a conductive material are twisted together; and the insulation covering that covers the outer circumference of the conductor, the method comprising:
a partial exposure step of providing the exposed portion in which the insulation covering is removed from the outer circumference of the conductor, and the covered portion in which the insulation covering covers the outer circumference of the conductor, the exposed portion and the covered portion being provided adjacent to each other in the longitudinal axis direction of the insulated electric wire;
a filling step of filling gaps between the plurality of elemental wires in the exposed portion with the water-stopping agent made of a curable resin composition; and
a curing step of curing the water-stopping agent placed in the exposed portion while rotating the insulated electric wire around an axis of the insulated electric wire.
