Claim 0:
1. An insulated electric wire comprising:
a conductor in which a plurality of elemental wires made of a metal material are twisted together; and
an insulation covering that covers an outer circumference of the conductor;
wherein the insulated electric wire further comprises:
an exposed portion in which the insulation covering is removed from the outer surface of the conductor; and
a first covered portion and a second covered portion in which the insulation covering covers the outer circumference of the conductor,
the first covered portion, the exposed portion, and the second covered portion being adjacent to each other in a direction of a longitudinal axis of the insulated electric wire in this order,
a water-stopping portion being further provided in at least an area extending from a part of the exposed portion to a part of the first covered portion, gaps between the elemental wires in the water-stopping portion being filled with a water-stopping agent, and
a region of the second covered portion that is adjacent to the exposed portion being a non-waterproof end that has a void between the conductor and the insulation covering, wherein
in the second covered portion, an outer diameter of the conductor is smaller in an area of the non-waterproof end adjacent to the exposed portion than in a remote area that is distanced from the exposed portion.
