Summary:PROBLEM TO BE SOLVED: To provide a rotating electrical machine improved in thermal conductivity to secure the electric characteristics even when a coil insulator is oriented and arranged in the edgewise direction of an insulating layer. SOLUTION: The rotating electrical machine is provided with: a conductor bundle constituted by bundling conductors and arranged in a core slot; and a coil insulator having an insulation between conductors and a main insulation surrounding the conductor bundle with respect to the slot. The coil insulator includes: a mica layer consisting of at least one of a peeling mica and a laminated mica, a fabric consisting of at least either one of an inorganic substance and an organic substance, a powder of hexagonal boron nitride having a crystallization index of 1.8 or more, and a thermosetting polymeric organic resin integrating the mica layer and the powder of hexagonal boron nitride. The powder of hexagonal boron nitride is orientated and arranged in the coil longitudinal direction. COPYRIGHT: (C)2010,JPO&INPIT
