A stator core for use in a cylinder linear motor has a positioning rod 48 and a plurality of core bodies 42. The positioning rod 48 extends in a rod shape, and a plurality of recesses 480 are formed at predetermined intervals in the extension direction. The plurality of core bodies 42 are formed in a flat plate shape, and a hole 421 in which a movable element can be inserted is formed in a direction orthogonal to the flat plate. In the outer circumference of the plurality of core bodies 42, fitting parts 422 which fit in the recesses 480 are provided.
