PROBLEM TO BE SOLVED: To provide a permanent magnet type rotor which can reduce an eddy current loss. SOLUTION: The permanent magnet type rotor includes an insulating film 31 made of an electric insulator provided on a surface of a split magnet 12a, and a metal plating layer 32 covering only a predetermined region brought into contact with a laminated core formed of a magnetic steel sheet or a predetermined region brought into contact with the laminated core and only a predetermined peripheral region of the predetermined region. The predetermined region brought into contact with the laminated core on the front surface 31A of the insulating film 31 is formed as a contact part 31a brought into contact with a magnet holding pawl part 22a of a salient pole 22 when the split magnet 12a is mounted between the adjacent salient poles 22 and 22 in a circumferential direction and a bent part 31b bent in a substantially protruding part in a direction toward an outer part from an inner part of the split magnet 12a.
