Abstract
An oscillator oscillates a terahertz wave of a frequency fdefined by a microstrip resonator configured such that a negative resistance element and a dielectric body are sandwiched between two conductors. The oscillator includes a resistance element disposed in parallel to the negative resistance element. The resistance element is disposed in a position corresponding to a node of an electric field stably existing in the resonator in the frequency fof the oscillated terahertz wave.
