A yoke of a motor has a bottom and an open end and accommodates an armature. An end bracket substantially closes the open end of the yoke. A connector portion, which bulges outward of the yoke, and a cutout portion are formed in the circumferential wall of the end bracket. A pair of feed members is provided to extend from the interior of the end bracket to the connector portion through the cutout portion. The end bracket has an accommodation recess for accommodating the noise suppression element at a position corresponding to the cutout portion. Each feed member has an accommodation recess corresponding portion, which corresponds to the accommodation recess, and a cutout portion corresponding portion, which corresponds to the cutout portion. The distance between the accommodation recess corresponding portions of the feed members is greater than the distance between the cutout portion corresponding portions.

A plasma processing apparatus includes a processing chamber, a stage, a dielectric member, a microwave introduction device, an injector, and an electric field shield. The processing chamber has a processing space therein. The stage is provided within the processing chamber. The dielectric member has a through hole and is provided to face the stage. The microwave introduction device is configured to introduce microwave into the processing space via the dielectric member. The injector has at least one through hole and is made of a dielectric material, e.g., a bulk dielectric material. The injector is provided within the dielectric member. The injector and the through hole of the dielectric member form a path for supplying a processing gas into the processing space. The electric field shield encloses the injector.
