The present invention addresses the problem of suppressing high-frequency noise radiated from a radiation antenna in a high-frequency radiation plug, wherein the radiation antenna is provided to one end of a casing. The present invention is a high-frequency radiation plug comprising: a transmission line that transmits electromagnetic waves; a radiation antenna for radiating the electromagnetic waves supplied via the transmission line; and a casing that is configured from a cylindrical conductor, has one end provided with the radiation antenna, and accommodates the transmission line extending from the radiation antenna to the other end side. The high-frequency radiation plug is characterized in that the transmission line is configured by embedding in an insulator, inside the casing, a center conductor that is electrically connected to the radiation antenna, and an outer conductor that surrounds the center conductor with a space therebetween, and the outer conductor is provided in a state of non-contact with the casing. |
