1. An oscillator, comprising:an oscillator circuit, configured to output a plurality of oscillation signals using a crystal resonator; and
a substrate, connected to the oscillator circuit, wherein the substrate includes:
a first crystal resonator land and a second crystal resonator land that are electrically connected to the crystal resonator;
a power source land, electrically connected to a power source; and
a first output land, positioned between the first crystal resonator land and the power source land to output a first oscillation signal from the oscillator circuit to an outside, wherein,
a first wiring pattern from the first output land is wired toward a direction and passes through between the first crystal resonator land and the second crystal resonator land, and
a second wiring pattern from the power source land is wired toward the direction.
