PROBLEM TO BE SOLVED: To provide a canned motor, capable of realizing improvement in motor efficiency by preventing the occurrence of an eddy current of a can and by suppressing the increase in wall thickness. SOLUTION: The canned motor has following constitution: a rotor core 8 of a rotor 7 is arranged to the inner peripheral part of a stator core 3 of a stator 1; the can 13, which segregating the stator 1 from the rotor 7, is arranged between the rotor 7 and the stator 1; the can 13 is formed, by applying compression molding to a thermosetting resin so that the wall thickness of a drum part 13b, located at an air gap part between the stator core 3; and the rotor core 8 is made thinner than a flange part 13c which is the other part.
