    • PROBLEM TO BE SOLVED: To provide a surface magnet type rotating electric machine and a manufacturing method thereof, capable of suppressing the generation of eddy current loss while suppressing an assembly process from being complicated.
      SOLUTION: This surface magnet type rotating electric machine includes a rotor 310, and the rotor 310 includes a magnet 311 and a scattering prevention pipe 312 which is installed on the outer periphery of the magnet 311 and which prevents the magnet 311 from scattering. The scattering prevention pipe 312 is formed by sintering titanium composite material where a first portion 312A as a titanium layer and a second portion 312B as a silicon particle layer having specific resistance higher than the first portion 312A are alternately layered in the axial direction.
