ABSTRACT:
A quartz-crystal oscillator has a configuration wherein a rectangular container1accommodating a piezoelectric oscillator device5therein is fixed to a rectangular supporting substrate6on which an IC device7is mounted via spacer members12formed of metal bodies. On the surface of the supporting substrate6, part or all of the IC device7and side faces of the spacer members are coated with a resin material. When the quartz-crystal oscillator is implemented on a main board by soldering or the like, the problem that the solder for bonding the quartz-crystal oscillator to the main board is adhered to the spacer members12, thereby causing a short-circuit can be effectively prevented.
