Abstract:
The cable according to one embodiment of the invention comprises: one or a plurality of core members, each having a conductor and an insulation cover material covering the conductor; and a sheath layer covering the one or the plurality of core members. The sheath layer comprises an inner sheath layer, and an outer sheath layer covering the inner sheath layer. The inner sheath layer comprises a crosslinked very low density polyethylene. The main component of the outer sheath layer is polyurethane. Relative to 100 parts by mass of resin component in the inner sheath layer, the very low density polyethylene content is between 20 parts by mass and 100 parts by mass inclusive. The elastic modulus of the inner sheath layer at 25° C. is between 5 MPa and 30 MPa inclusive.
