Abstract

Disclosed is an insulated wire which comprises a conductor, a first insulating metal oxide layer which is formed around the conductor, and a second insulating metal oxide layer, containing ceramics particles mixed by addition, which is formed around the first insulating metal oxide layer. The aforementioned insulating metal oxide layers can be formed by changing a precursor of a metal oxide to a ceramics state, using a method such as a sol-gel method or a thermal decomposition method.
Further, the mixed ceramics particles are more preferably in the form of a fine plate. This insulated wire is excellent in flexibility, emits no gas, can maintain insulation even under a high temperature, and has a high breakdown voltage.
