Abstract

A rotating electric machine according to embodiments is a rotating electric machine including a rotor including a first core and being capable of rotating around a rotating shaft; and a stator disposed to face the rotor in the axial direction of the rotating shaft, the first core including a first pressed powder material having a plurality of first flaky magnetic metal particles and a first intercalated phase, the first flaky magnetic metal particles having an average thickness of from 10 nm to 100 μm, each first flaky magnetic metal particle having a first flat surface and a first magnetic metal phase including at least one first element selected from the group consisting of Fe, Co, and Ni, the average value of the ratio of the average length in the first flat surface with respect to the average thickness being from 5 to 10,000, the first intercalated phase existing between the first flaky magnetic metal particles and including at least one second element selected from the group consisting of oxygen (O), carbon (C), nitrogen (N), and fluorine (F), wherein in the first pressed powder material, the first flat surfaces are oriented approximately in parallel with a first principal plane of the first pressed powder material and have the difference in magnetic permeability on the basis of direction within the first principal plane, and the first principal plane of the first pressed powder material is disposed to be approximately perpendicular to the radial direction of the rotating electric machine.
