An oscillator includes a phase shifter and a power distributor which are disposed in a dielectric substrate comprising a plurality of stacked dielectric layers. The phase shifter comprises a coupler and a reflecting circuit. The dielectric substrate has a first formation region containing a plurality of electrodes serving as the coupler, a second formation region containing a plurality of electrodes serving as the reflecting circuit, and a third formation region containing a plurality of electrodes serving as the power distributor. The first formation region, the second formation region, and the third formation region are disposed in respective positions that are spaced from each other in a plane within the dielectric substrate.
