Abstract: An electrode with a conduit includes: a tubular portion internally provided with a first conduit; a distal end portion provided at the distal end of the tubular portion; a second conduit that is provided inside the distal end portion, the second conduit being configured to communicate with the first conduit; an opening configured to communicate with the first conduit and the second conduit; a first hemostatic surface that has a flat surface extending from the distal end of the tubular portion in an extending direction of the second conduit, and serves as an electrode configured to cause a high-frequency current to flow through a biological tissue; and a second hemostatic surface that is connected to a distal end side of the first hemostatic surface and is provided at an end portion protruding toward a distal end side from the opening.

Abstract: A high frequency antenna module having a substrate, a feeding electrode and two dielectric chip antennas being mounted on said substrate. Each of the two dielectric chip antennas having a base end connected to the feeding electrode and a floating end as an open end. A distance between said open ends of the two dielectric chip antennas is shorter than a distance between said base ends of the two dielectric chip antennas.

Abstract: An antenna device comprising: a substrate; a radiation portion including a dielectric block arranged on one principal face of said substrate and a first conductor layer formed in a stereoscopic shape on a surface of said dielectric block; and a grounding conductor including a second conductor layer provided on other principal face of said substrate.

Abstract: A multiple band antenna comprising: a dielectric substrate; and a plurality of antenna elements being formed of each a conductor on a same face of the dielectric substrate and provided in a one-to-one correspondence with frequency bands to operate the frequency bands, wherein each of the antenna elements has an open end as one end and is connected at an opposite end to a feeder line and comprises a narrow part being placed on a side of the open end and formed by line with a narrow wide and a wide part being placed on a side of the feeder line and having a wider width than the narrow wide of the narrow part, the narrow part is turned in order in substantially the same direction as a width direction of the wide part, to form a meander shape, and the antenna elements have the wide parts joined in one piece forming a predetermined angle with each other so as to share a part of the wide parts.
