Abstract

An electrically insulated cable comprising: a core electric wire; a tape member covering the core electric wire; and a covering layer covering the tape member, wherein: the core electric wire includes a plurality of insulated electric wires; the insulated electric wires each include a conductor and an insulating layer covering the conductor; the tape member is a film; and the tape member has a breaking elongation of 50% or less.

Claims (17)

1 . An electrically insulated cable comprising:

a core electric wire;

a tape member covering the core electric wire; and

a covering layer covering the tape member;

wherein:
