A permanent magnet type rotating electric machine includes: a rotor including a rotor core and a plurality of permanent magnets; and a stator including a stator core and armature windings, in which, when the number of poles is M, the number of slots is N, M permanent magnets are sequentially numbered from first to M-th in a circumferential direction, and a shape deviation shift amount in the circumferential direction for an i-th (i=l, 2, ..., M) permanent magnet is c, M unit vectors in total, each being in an angular direction of 2nN(i-l)/M (rad), are defined, and a sum of M vectors obtained by multiplying the unit vectors respectively by the positional shift amount cis smaller than a maximum value of an absolute value of the positional shift amount c, the shape deviations of the plurality of permanent magnets are made in directions opposite to each other for the neighboring permanent magnets.
