PROBLEM TO BE SOLVED: To provide an inexpensive airtight electric wire and its manufacturing method with easy terminal working and superior productivity capable of positively preventing leakage from an electric wire terminal part and infiltration of oil, water, or the like into an electric wire interior by a capillary phenomenon. SOLUTION: This airtight electric wire comprises a stranded wire conductor formed with an airtight part at least in one part in the longitudinal direction and an insulator covered on an outer circumference of the stranded wire conductor. It is characterized by that the stranded wire conductor has a plurality of conductive element wires and a filler comprising thermosetting polymer as a mandatory, composition, the conductive element wires are arranged in an outermost layer, and space between each conductive element wire is penetrated by hardened objects of the filler at the airtight part of the stranded wire conductor. |
