Abstract
An oscillation element that oscillates an electromagnetic wave includes a negative resistance element and a resonator including a first conductor and a second conductor, in which the negative resistance element and the resonator are arranged on a substrate, the negative resistance element is electrically connected to the first conductor and the second conductor, the first conductor and the second conductor are capacitively coupled to each other, and when a capacitance between the first conductor and the second conductor is set as C, an inductance of the first conductor and the second conductor is set as L, a speed of the oscillated electromagnetic wave in vacuum is set as C, a relative dielectric constant of the substrate is set as ε, and a diagonal line length of the substrate is set as d, a series resonant frequency fof the resonator satisfies f=1/{2π√(LC)}, and f<C/[d√{(1+ε)/2}].
