Abstract
A surface mounting quartz-crystal oscillator having a container body formed with a recess of which a pair of opposite sidewalls are provided with steps, a quartz blank, an IC (integrated circuit) chip constituting an oscillating circuit including a quartz crystal member made of the quartz blank, and a cover closing the container body for sealing the quartz blank and the IC chip within the container body. At least one of the both ends of the quartz blank is bonded to the bottom face of the recess, and the opposite ends of the IC chip are held to the steps. A space is defined between the IC chip and the bottom face of the recess for permitting at least a part of the quartz blank to be disposed in the space.
