A magnetically actuated MEMS switchincludes a first magnetic core portion, a first signal line, a first contact point, a second magnetic core portion, a second signal line, a second contact point, and a first coil portionand a second coil portionserving 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 portionand the second magnetic core portion. The first contact pointis 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 pointand the second contact pointare switched in response to displacement of the first contact point
