A resin composition containing 0.0 parts by weight is applied onto the conductor. A thin insulated wire having an insulating layer formed by extrusion coating to a thickness of 3 mm or less, and a polyfunctional monomer of 1 to 2 parts per 100 parts by weight of the vinyl chloride resin in the vinyl chloride resin composition.
A resin composition containing 0.0 parts by weight is applied onto the conductor. 3 m
A thin insulated wire with an insulator layer made of a cross-linked material coated by extrusion and cross-linked with radiation after being extruded to a thickness of less than It has been found that the properties (scrape abrasion value) are even more excellent, and the effect of improving productivity can also be obtained. In addition, the scrape abrasion value refers to the scrape wear value when a hard chrome-plated steel blade with a 0.125R edge is used on a thin insulated wire at a load of 0.9 kg and one stroke of 10 mm (20 mm reciprocation).
) is the number of reciprocations until dielectric breakdown occurs in the insulator layer when the insulator layer is reciprocated at a rate of 60 reciprocations/min.

At least 1 part by weight is added to 100 parts by weight of vinyl chloride resin. If the blending amount is less than 1 part by weight, the effect of improving the scrape abrasion characteristics of the resulting insulator will be low.

If the amount is less than ffi parts, the crosslinking reaction will not proceed sufficiently. Moreover, when it exceeds 20 parts by weight, the degree of crosslinking reaches saturation, and the insulating layer becomes brittle.
