PROBLEM TO BE SOLVED: To provide an element which allows for more stable oscillation of terahertz waves of a desired oscillation frequency f, by reducing parasitic oscillation due to the wiring structure.SOLUTION: An oscillator is an element for oscillating or detecting terahertz waves, and includes a resonance section 102 having a differential negative resistance element 101, a first conductor 103, a second conductor 104, and a dielectric 105a, a bias circuit 120 for supplying a bias voltage to the differential negative resistance element, and a line 108 connecting the resonance section and the bias circuit. The differential negative resistance element and dielectric are arranged between the first conductor and second conductor, and the line is a low impedance line with reference to the absolute value of differential negative resistance of the differential negative resistance element, at the frequency fof resonance by the inductance of the line and the capacitance of the resonance section. |
