Abstract
A detecting devicedetects an elastic wave propagating through the air. The detecting deviceincludes: a first electrodethat is a plate having a cantilever structure with a fixed end FX and a free end FR and that vibrates by being bent by the elastic wave; and a second electrodethat is a plate, that is opposed to the first electrode, and that has a predetermined distance from the first electrode. The detecting devicedetects the elastic wave on the basis of a change in capacitance between the first electrode and the second electrode. An end of the second electrodein a direction from the fixed end FX to the free end FR is closer to the fixed end than the free end.
