A conductive portion of a circuit body is formed by performing spraying on a surface of a resin casing. For spraying of the conductive portion, a cold spray method in which metal powder and inert gas are sprayed to an object is used. A circuit component is mounted on the conductive portion. Each terminal portion of the conductive portion is provided with a connector for connection with an external circuit body. An insulating resin is laminated on a surface of the conductive portion. The circuit body is directly formed on the surface of the resin casing by a series of processes described above.

The present invention relates to a surface modified overhead conductor with a coating that allows the conductor to operate at lower temperatures. The coating contains about 5% to about 30% of an inorganic adhesive, about 45% to about 92% of a filler, about 2% to about 20% of one or more emissivity agents, and about 1% to about 5% of a stabilizer.

A method for manufacturing a terminal-equipped electric wire includes a step of crimping a terminal to one end of an electric wire, a step of crimping another terminal to the other end of the electric wire, and a waterproofing step of providing a sealing member at the other end of the electric wire so as to fill gaps between conductive element wires of an element wire bundle.
