Abstract
An inverter surge-resistant insulated wire comprising a conductor and an enamel resin-insulating laminate that has a foamed region including cells and a non-foamed region including no cells on at least one surface of the foamed region on the conductor, wherein the foamed region is configured such that a non-cell layer including no cells has cell layers formed of closed cells on both surface sides of the non-cell layer, a thickness of the non-cell layer is larger than a thickness of a partition wall among the closed cells, and 5 to 60% of a thickness of the foamed region, and at least 10 the cell layer in the foamed region is formed of a thermosetting resin; an inverter surge-resistant insulated wire having a conductor and the enamel resin-insulating laminate; and electric/electronic equipment.
