PROBLEM TO BE SOLVED: To provide a board for an oscillator using printed resistors sharable with a VCXO and a PXO. SOLUTION: The board for the oscillator is usable for the PXO comprising a crystal resonator Y1 and a crystal oscillation circuit 11 or for a VCXO comprising a piezoelectric oscillation circuit and a frequency voltage control circuit 12, and resistive components of the VCXO employ the printed resistors except a resistor R2 which is replaced with a short-circuit component to change the VCXO into the PXO. Since the board 21 for the oscillator can be used in common between the VCXO and the PXO in this way, a cost-reduced oscillator can be obtained. Further, since the resistors except the resistor R2 for changing the VCXO into the PXO employ the printed resistors, it is possible to downsize the piezoelectric oscillator.
