The present invention provides a linear motor in which the loss of the motor is reduced and a motor efficiency is improved. A linear motor includes: a mover part including an armature module having an I shaped magnetic iron core ( 1 ) and an armature winding ( 2 ) of one kind wound on the periphery of the I shaped magnetic iron core ( 1 ) through an insulating resin ( 3 ), a non-magnetic material holder ( 4 ) on which a plurality of armature modules are arranged in a stroke direction, and a base upper plate ( 8 a) and a base lower plate ( 8 b) for attaching the non-magnetic material holder ( 4 ) in its upper and lower parts respectively; and a stator part including a plurality of field permanent magnets ( 10 ) opposed to the I shaped magnetic iron cores ( 1 ) through magnetic spaces and field yokes ( 9 ) for supporting the field permanent magnets ( 10 ). The non-magnetic material holder ( 4 ) has through holes ( 41 ) corresponding to the forms and the arranging pitches of the I shaped magnetic iron cores ( 1 ) and bolts ( 5 ) are inserted into the through holes ( 41 ) to fix the non-magnetic holder to the base upper plate ( 8 a) and the base lower plate ( 8 b).
