Disclosed is a linear motor which includes a stator and a mover. The stator extends along a first axis. The mover is arranged so as to extend along the first axis and radially face the stator. The mover has a pole interval along the first axis different from that of the stator. At least one of the stator and the mover has a plurality of permanent magnets arranged in alignment with each other along the first axis, and a plurality of yoke parts arranged in alignment with each other along the first axis. The permanent magnets are provided, for each pole, in a continuous range along the first axis. The permanent magnets are polar anisotropic magnets that are magnetized from both end portions along the first axis to a radial end portion at a center along the first axis, or magnetized in the reverse directions to these.
