An object of the invention is to provide a coreless linear motor which can suppress the increase in the temperature of an armature winding. There is provided a coreless linear motor in which a slider ( 10 ) is made up of an armature winding ( 11 ) which comprises a plurality of coils ( 13 ) and a slider mounting table ( 12 ) which supports the armature winding ( 11 ), and a stator ( 1 ) is made up of permanent magnets ( 2 ) which form a plurality of magnetic poles and back yokes 3, and, furthermore, in which both left and right sides of the armature winding ( 11 ) is sandwiched by the permanent magnets ( 2 ) via a gap, the coreless linear motor being characterized in that a concave portion ( 12 a) is provided in a lower side of the slider mounting table ( 12 ), and in that a coil upper side ( 14 ) which corresponds to an upper side of the coil ( 13 ) is inserted in the interior of the concave portion ( 12 a) in the slider mounting table ( 12 ) and a space is provided in the vicinity of a coil lower side ( 15 ) which corresponds to a lower side of the coil ( 13 ) for performing a connecting process between the coils ( 13 ) or the coil ( 13 ) and a lead wire ( 16 ).
