Laminate of conductor and insulating film, coil, and rotating electrical machine

Provided is a laminate having excellent partial discharge resistance. A laminate provided with at least a conductor and an insulating coating film formed on the conductor, the insulating coating film having at least a first insulating layer and a second insulating layer in this order from the conductor side, the first insulating layer comprising a resin composition containing a metal oxide, and the second insulating layer comprising a resin composition containing a metal oxide. The second insulating layer is composed of a resin composition containing a metal oxide hydrate. 本发明提供一种耐局部放电特性优异的层叠体。一种层叠体，至少具备导体和形成于所述导体上的绝缘被膜，所述绝缘被膜至少从所述导体侧起依次具有第一绝缘层和第二绝缘层，所述第一绝缘层由包含金属氧化物的树脂组合物构成，所述第二绝缘层由包含金属氧化物水合物的树脂组合物构成。
