Kind Code:
A1
Abstract:
Provided are an insulating laminated body of enamel resin, and an inverter-surge resistant insulated wire and an electric appliance that include the insulating laminated body of enamel resin and a conductor. The insulating laminated body of enamel resin is formed to have a flat or tubular shape and provided with a foam region and a non-foam region on at least one surface of the foam region. The foam region is configured to include a bubble-free layer that does not contain bubbles, and, on both surface sides of the bubble-free layer, bubble layers comprising independent bubbles. The thickness of the bubble-free layer is thicker than the thickness of the partitions between the independent bubbles, and 5-60% of the thickness of the foam region. At least the bubble layers of the foam region are formed from a heat-curable resin.
