が好ましい。The resin used in the present invention has a fluidity with as low a viscosity as possible when injected so that it can easily penetrate into the narrow stranded conductor, and once it has penetrated, it does not easily flow out and then hardens and flows. It is necessary that the resin loses its properties. Furthermore, in order to prevent the flexibility of the insulated wire itself from being impaired, it is essential for the resin after curing to have an elasticity D50 or less, and any resin that affects such performance is included in the present invention. Vine used for a purpose. Furthermore, it is preferable that the resin used in the present invention has an elongation of 200% or more after curing.

く向上させることが可能となった。(Effects of the Invention) As explained above, the waterproof structure of the insulated wire according to the present invention uses less resin (1/100 or less of the conventional one), is small, and facilitates work such as f=J. Furthermore, the voids between the stranded wire conductors near the peeled portion of the insulated wire and its surroundings, and the voids between the stranded wire conductors and their coating near the peeled portion of the insulated wire are filled with the cured resin. Therefore, the peeled part caused by peeling of the insulation coating and the surrounding area (for example, 10 minutes from the cut end of the insulation coating)
All voids (over 0 m+) are eliminated, preventing water and salt water from entering those areas, and preventing free passage inside the conductor.
I was able to do L. As a result, it has become possible to prevent corrosion of the conductor, melting and disconnection of the connected portion, and to significantly improve the durability of the insulated wire.
