摘要： Provided is a layered body comprising a conductor and an insulation film containing a metal hydroxide hydrate, wherein properties such as electrical characteristics and physical characteristics can be improved while maintaining an erosion suppressing effect against partial discharge, and manufacturing costs can be reduced. The layered body comprises at least a conductor and an insulation film, wherein: the insulation film includes a first insulation film and a second insulation film; the second insulation film is constituted by a resin composition comprising a metal oxide hydrate; in the resin composition, the content of the metal oxide hydrate is 6-50 parts by mass with respect to 100 parts by mass of the resin; the thickness of the second insulation film is 5 μm or more; the ratio of the thickness of the second insulation film is less than 75% of the thickness of the entire insulation film; and in the insulation film, an inorganic insulation layer is formed when the layered body is exposed to a partial discharge generated by an inverter surge.
