Provided are rotor of permanent magnet surface affixation-type rotating machine and its manufacturing method, where permanent magnets previously magnetized are easily fixable at proper positions while restricting cost. In rotor of permanent magnet surface affixation-type rotating machine, including cylindrical rotor shaft 11, columnar guides 13 extending along axial direction of rotor shaft 11 and disposed in circumferential direction at regular intervals, and permanent magnets 12 previously magnetized and installed on surface of rotor shaft 11 and between the adjacent guides 13, axial length of guide 13 is formed longer than that of region where permanent magnets 12 are installed, guide 13 is disposed on surface of rotor shaft 11 such that guide 13 projects toward both sides in axial direction from region where permanent magnets 12 are installed, and projection portions 13a, 13b projecting in axial direction from region where permanent magnets 12 are installed are fixed to rotor shaft 11.
