Claim:
1. An oscillation circuit comprising: a circuit for oscillation that is connected to a resonator and oscillates the resonator; an output circuit that has a signal, output from the circuit for oscillation, input thereto to thereby output an oscillation signal; a pad to which power is applied; a first wiring that connects from the pad to the output circuit; and a second wiring that is connected to the first wiring at a connection node provided on the first wiring, the second wiring extending from the connection node to the circuit for oscillation, the connection node being disposed at an intersection of the second wiring, a first portion of the first wiring extending from the connection node to the output circuit, and a second portion of the first wiring extending from the connection node to the pad, wherein the circuit for oscillation, the output circuit, the pad, the first wiring, and the second wiring are provided on a semiconductor substrate, a length of the second portion of the first wiring is shorter than a length of the second wiring, the length of the second portion of the first wiring is shorter than a length of the first portion of the first wiring, and the length of the second wiring from the connection node to the circuit for oscillation is longer than a length of the first wiring from the pad to the output circuit.
