Abstract
The object of the present invention is to improve the production efficiency by making its bonding process unnecessary to simplify the production process. The method of production comprises the step of integrally incorporating a magnetic material when the stationary holders and of the stationary member and the movable holder of the movable member are molded with a non-magnetic material such as a plastic material and the like. Therefore, a magnet unit in which the stationary magnets and or the movable magnet is integrally incorporated into the stationary holders and or the movable holder can be provided only by giving magnetization treatment on the magnetic material without using a bonding process.
