PROBLEM TO BE SOLVED: To provide a dynamo-electric machine capable of suppressing the lowering of the cooling capacity of a permanent magnet. SOLUTION: The dynamo-electric machine includes a rotating shaft rotatably mounted thereon. It includes a rotor core 121 fixed to the rotating shaft, wherein hole sections are formed. It further includes the permanent magnets 122 buried in parts of the hole sections. A refrigerant that cools the permanent magnets 122 is made to flow in spaces 121B as parts of the hole sections formed to the rotor core 121. The permanent magnets 122 are bonded and fixed onto the inner wall surfaces of the hole sections while interposing adhesive layers 124 containing sheet-shaped base materials.
