PROBLEM TO BE SOLVED: To materialize a linear motor which is small and has a high efficiency by easily and precisely laminating electromagnetic steel plates 22 having projections 30 on them. SOLUTION: The laminated stator core 14 of the linear motor 10 consists of two kinds of the electromagnetic steel plates 22 which are formed in a specified shape having each a plurality of projections 30 in the same direction at the outer side portions of the center and are alternately laminated in radial by avoiding a lap of these projections 30.
