1. An insulated electric cable comprising:
two first core wires, each of the two first core wires including:
a first conductor; and
a first insulating layer covering the first conductor;
two second core wires, each of the two second core wires including:
a second conductor having a cross-sectional area smaller than that of the first conductor; and
a second insulating layer covering the second conductor; and
a coating layer covering the first core wires and the second core wires,
wherein the two second core wires are mutually stranded to form a subunit, and
wherein one of the two first core wires, another of the two first core wires, and the subunit are mutually stranded.
