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 11 A and a second claw pole type yoke unit 11 B are arranged for a pair of linear portions 9 a of a coil 9 , respectively. The first and second claw pole type yoke units 11 A and 11 B are arranged so that first pole teeth 15 of the first claw pole type yoke unit 11 A face second pole teeth 17 of the second claw pole type yoke unit 11 B and the second pole teeth 17 of the first claw pole type yoke unit 11 A face the first pole teeth 15 of the second claw pole type yoke unit 11 B. Permanent magnet rows 19 A to 19 C are interposed between the first claw pole type yoke unit 11 A and the second claw pole type yoke unit 11 B of corresponding coil units 7 A to 7 C, respectively, so that both sides of each of the permanent magnet rows 19 A to 19 C face the first and second pole teeth 15 and 17 of the first and second claw pole type yoke units 11 A and 11 B, respectively.
