Permanent magnet embedded type rotating electric machine

The purpose of this invention is to obtain a permanent magnet embedded type rotating electric machine in which the amount of magnetic flux of a permanent magnet can be prevented from reducing and the permanent magnet can be effectively cooled. In the permanent magnet embedded type rotating electric machine, a rotor (15) has: a rotor iron core (17) constructed by laminating and integrating magnetic steel sheets and firmly fixed to a shaft; a plurality of magnet housing openings (20) each formed so as to penetrate in an axial direction on the outer circumferential side of the rotor iron core (17) and disposed in a circumferential direction; and permanent magnets (21) housed in the respective magnet housing openings (20). An adhesive agent (22) is disposed only between the outside wall surface (20a) of the inner wall surfaces of each of the magnet housing openings (20), which is positioned outward in the radial direction, and the outside surface (21a) of the surfaces of each of the permanent magnets (21), which is positioned outward in the radial direction. The permanent magnets (21) are each disposed one-sided to the outside wall surface (20a) of each of the magnet housing openings (20) and fixed. A cooling flow path (23) through which a refrigerant flows is constituted by the inside surface (21b) of the surfaces of each of the permanent magnets (21), which is positioned inward in the radial direction, and the inside wall surface (20b) of the inner wall surfaces of each of the magnet housing openings (20), which is positioned inward in the radial direction.
