By reviewing the material of the forcer housing of a rod-type linear motor and the assembly structure of a coil member of the forcer housing, the thrust is increased, an optimum shape can be easily given to the forcer housing depending on the use purpose, and the linear motor can be manufactured at low cost. The linear motor comprises a magnet rod composed of many magnetic poles arranged with predetermined pitches along the axis and a forcer having a through hole into which the magnet rod is freely fitted and reciprocatable relatively to the magnet rod according to an applied electric signal. The forcer is composed of a forcer housing in which the through hole is made and a coil member which is arranged on the inner circumferential surface of the through hole of the forcer housing and to which the electric signal is applied. The forcer housing is formed by molding with a nonmetal inorganic material having an insulation property.
