Zusammenfassung:	According to the present technology, there is provided an oscillator that functions as a transformer-based LC oscillator including a first capacitor group connected in parallel to a primary-side winding of a transformer and forming a first LC tank together with the primary-side winding, and a second capacitor group connected in parallel to a secondary-side winding of the transformer and forming a second LC tank together with the secondary-side winding, the oscillator including: a first type capacitor bank that is a capacitor bank having a maximum variable capacity of a predetermined value or more, and a second type capacitor bank that is a capacitor bank having a maximum variable capacity of less than the predetermined value, as capacitor banks for oscillation frequency tuning, in which the first type capacitor banks are arranged in both of the first capacitor group and the second capacitor group.
