In the linear motor including (a) a plurality of permanent magnet members 1 fixed to a pair of ferromagnetic yokes 3 such that longitudinally adjacent magnetic poles have different polarities and that the magnetic poles of different polarities face each other via a magnetic gap 7, (b) a polyphase coil 2 disposed in the magnetic gap 7, either one of the polyphase coil 2 and the permanent magnet members 1 being caused to move relative to each other when the polyphase coil 2 is energized; and (c) a coil-supporting member 4 to which the polyphase coil 2 is fixed, the coil-supporting member 4 is made of non-magnetic ceramics having excellent heat conductivity and insulation.
