Title
(EN) INSULATED WIRE
Abstract
(EN)

An insulated wire comprising a conductor and a bubble-containing insulating layer, directly or indirectly coating the outer periphery of the conductor and containing a thermosetting resin, wherein the bubbles in the bubble-containing insulating layer include flattened bubbles whose oblateness in the cross-section perpendicular to the longitudinal direction of the insulated wire (lateral length of the bubble cross-sectional shape/vertical length of the bubble cross-sectional shape) is 1.5 or more and 5.0 or less.
