Linear motor and manufacturing method of linear motor
A linear motor comprise a pipe shaped member, and a stator stored in the pipe shaped member, the stator including plural magnets arranged in series so that adjacent poles of the plural magnets having the same magnetic pole are opposed each other, and a moving member capable of moving, the moving member being arranged to be opposed to an outer surface of the pipe shaped member, wherein the moving member includes an electro-magnetic coil and a coil holding member for holding at least a part of the outer surface of the electro-magnetic coil.
