Abstract
Provided is an electromagnetic field control member, the member including an insulating member made of a ceramic having a tubular shape and including a plurality of through holes extending in an axial direction; a conductive member that is made of a metal, seals off each of the through holes, and leaves an opening portion in the through hole, the opening portion opening to an outer periphery of the insulating member; and a power feed terminal connected to the conductive member. The through holes each include inner wall surfaces further including inclined surfaces for which a width between inner walls facing each other increases from an inner periphery of the insulating member to an outer periphery of the insulating member: and vertical surfaces that are located on an inner peripheral side of the insulating member and for which a width between inner walls facing each other is constant.
