摘要： A magnetically actuated MEMS switch 100 includes a first magnetic core portion 120, a first signal line 15, a first contact point 16, a second magnetic core portion 220, a second signal line 25, a second contact point 26, and a first coil portion 111 and a second coil portion 211 serving as a magnetic field applying portion that causes a current to flow in conductor coil to apply a magnetic field to the first magnetic core portion 120 and the second magnetic core portion 220. The first contact point 16 is displaced depending on the presence or absence of a magnetic field applied by the magnetic field applying portion. Connection and disconnection between the first contact point 16 and the second contact point 26 are switched in response to displacement of the first contact point 16.

摘要： A high-frequency transmission line in which the alternating-current resistance is low is provided. A high-frequency transmission line 2 is a high-frequency transmission line 2 to transmit an alternating-current electric signal, and contains metal and carbon nanotube, and the carbon nanotube is unevenly distributed at a peripheral part 8 of a cross-section that is of the high-frequency transmission line 2 and that is perpendicular to a transmission direction of the alternating-current electric signal.

摘要： A high-frequency transmission line in which the alternating-current resistance is low and that is hard to disconnect is provided. A high-frequency transmission line 2 is a high-frequency transmission line 2 to transmit an alternating-current electric signal, and contains metal and carbon nanotube, and the carbon nanotube is unevenly distributed at a central part 6 of a cross-section that is of the high-frequency transmission line 2 and that is perpendicular to a transmission direction of the alternating-current electric signal.

摘要： A MEMS switch includes a first signal line provided in a first beam, a first GND adjacent to the first signal line, a second signal line provided in a second beam, and a second GND adjacent to the second signal line. A contact terminal is fixed to any one of the first signal line and the second signal line and performs connection between the first signal line and the second signal line according to deformation of the first beam.
