PROBLEM TO BE SOLVED: To provide a piezo-oscillator that outputs two frequencies, and is free of variation in an oscillation frequency due to load variation even if output of one frequency is stopped.SOLUTION: A piezo-oscillating machine includes a first wiring pattern (NA) including a wire connecting one piezoelectric vibration chip-mounted pad and a first IC-mounted pad and a wire connecting the other piezoelectric vibration chip-mounted pad and a second IC-mounted pad, and a second wiring pattern (OA) including a wire connecting a first output terminal and a third IC-mounted pad and a wire connecting a second output terminal and a fourth IC-mounted pad. A pair of piezoelectric vibration chip-mounted pads (XT1, XT2) and first wiring patterns (N1, N2) are formed not to overlap with a second output terminal (G5) and second wiring patterns (H3, H6) when viewed from a normal direction of a mounting surface. |
