To provide an armature of a linear motor improvable in production efficiency at a process for connecting and fixing magnetic pole teeth, and reducible in weight.
Each of the first magnetic pole teeth 100 comprises a tooth part 101, a relay 102 and a press-insertion protruded piece 104 at the tooth protruding side of end faces of the relay 102. Each of the second magnetic pole teeth 200 comprises a tooth part 201, and a press-insertion recess 202 formed at the root of the tooth part 201. By making end face 103 of the adjacent first magnetic pole teeth 100 closely contact with each other, and by press-inserting the press-insertion recesses 202 of the second magnetic pole teeth 200 into press-insertion protrusions 105 formed of the press-insertion protruded pieces 104 of the adjacent first magnetic pole teeth 100, the first magnetic pole teeth 100, and the second magnetic pole teeth 200 are connected and fixed to each other.
