1. An insulated wire with bonding layer comprising:
a conductor;
an insulating coating layer that covers an outer circumference of the conductor; and
a bonding layer that is provided on an outer side of the insulating coating layer and is bonded by heat,
wherein the insulating coating layer contains polyvinyl chloride,
the bonding layer contains a modified polyolefin resin and a polyamide resin, and does not contain a polymer component apart from the modified polyolefin resin and the polyamide resin or contains only at most 30 parts by mass of the polymer component apart from the modified polyolefin resin and the polyamide resin with respect to 100 parts by mass of the total polymer components,
the modified polyolefin resin is obtained by introducing an ester group into a base polyolefin,
the polyamide resin is a nylon-based hot-melt resin, and
the nylon-based hot-melt resin has a structure of one of an amino acid, a dicarboxylic acid, and a diamine, and has a saturated aliphatic compound having 6 to 11 carbon atoms as a monomer.
