PROBLEM TO BE SOLVED: To provide a linear motor which can radiate heat generated from the coil of a moving member efficiently. SOLUTION: The linear motor comprising a moving member including a core having a yoke 1 and a plurality of teeth 2, and a coil 3 wound around the teeth 2 is provided with a heat radiation member 20 interposed between adjoining coils to be partially in contact with the side face of the coil 3 and having a structure 20a for radiating heat to the ambient air at a portion more outer than the portion interposed between the coils 3. Heat generated in the coil 3 is transmitted to the portion of the heat radiation member 20 between the coils 3, transmitted through the portion of the heat radiating member 20 to the end portion thereof, and radiated to the ambient air from the heat radiation structure 20a provided at the end portion.
