<p>A piezoelectric oscillator has a structure that allows for fine adjustment of the frequency after resin molding. The piezoelectric oscillator includes a resonator package (30), in which a piezoelectric resonator element is housed, and a semiconductor device (80), in which an oscillation circuit that is electrically connected to the resonator package (30) is incorporated. The resonator package (30) and the semiconductor device (80) are fixed to corresponding different surfaces of an island portion (12) of a lead frame (10), and resin molding is performed so that a transparent lid (39) of the resonator package (30) is exposed to the outside.</p> |
