Abstract
A quartz-crystal oscillator has a configuration wherein a rectangular container 1 accommodating a piezoelectric oscillator device 5 therein is fixed to a rectangular supporting substrate 6 on which an IC device 7 is mounted via spacer members 12 formed of metal bodies. On the surface of the supporting substrate 6, part or all of the IC device 7 and 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 members 12, thereby causing a short-circuit can be effectively prevented.
