1. An oscillator comprising:
a first resonator element;
a circuit element configured to oscillate the first resonator element to generate an oscillation signal;
a first package which includes a substrate, and has a housing space configured to house the first resonator element and the circuit element at one principal surface of the substrate;
a second resonator element which is disposed at another principal surface of the substrate, and an oscillation frequency of which is controlled based on the oscillation signal;
a leg part which is disposed at the another principal surface of the substrate, and which is arranged so as to surround the second resonator element in a plan view of the substrate;
an external terminal disposed on a top surface of the leg part; and
an interconnection which is arranged inside the leg part, and which is electrically coupled to the external terminal.
