A linear motor capable of reducing thickness thereof in a direction orthogonal to a moving direction of a movable element therein is provided. A first claw pole type yoke unit 11A and a second claw pole type yoke unit 11B are arranged for a pair of linear portions 9a of a coil 9, respectively. The first and second claw pole type yoke units 11A and 11B are arranged so that first pole teeth 15 of the first claw pole type yoke unit 11A face second pole teeth 17 of the second claw pole type yoke unit 11B and the second pole teeth 17 of the first claw pole type yoke unit 11A face the first pole teeth 15 of the second claw pole type yoke unit 11B. Permanent magnet rows 19A to 19C are interposed between the first claw pole type yoke unit 11A and the second claw pole type yoke unit 11B of corresponding coil units 7A to 7C, respectively, so that both sides of each of the permanent magnet rows 19A to 19C face the first and second pole teeth 15 and 17 of the first and second claw pole type yoke units 11A and 11B, respectively.
