An armature of a linear motor includes a plurality of first magnetic teeth and a plurality of second magnetic teeth, each of the magnetic teeth being formed by laminating multiple tooth elements made of electromagnetic steel sheets. The first magnetic teeth are arranged side by side in a linear form while the second magnetic teeth are located one each between the successive first magnetic teeth. Each of the second magnetic teeth interconnects the two adjacent first magnetic teeth located on both sides.
