Provided is an electromagnetic wave emitting device (30) capable of switching amongst a plurality of terminal antennae (41) to a terminal antenna (41) for supplying electromagnetic waves, wherein the controllability of the timing of switching is improved. A switching apparatus (33) contains: a cavity resonator (50) in which a resonance space (60) is formed; an input side antenna (51) for emitting inputted electromagnetic waves, generated by an electromagnetic wave oscillator (32), to the resonance space (60); a plurality of output side antennae (52), which are provided to correspond with each terminal antenna (41), and which receive the electromagnetic waves to be output to the corresponding terminal antenna (41) within the resonance space (60); and adjustment mechanisms (53) which adjust the conductivity and the electrical characteristics of transmission lines (55), and one of each of which is provided to each of the electromagnetic wave transmission lines (55) that connect the output side antennae (52) with the terminal antenna (41). The switching apparatus (33) controls the adjustment mechanism (53) to switch to a transmission line (55), amongst the plurality of transmission lines (55), through which electromagnetic waves flow, thus switching the output side antenna (52) for receiving electromagnetic waves within the resonance space (60).
