ABSTRACT:
A surface mount type crystal oscillator includes: a container body composed of a laminated ceramic including a plate-shaped center layer, and first and second frame layers stacked on opposite surfaces of the center layer respectively; a crystal blank hermetically sealed in a first recess formed by the first frame layer and the center layer; an IC chip accommodated in a second recess formed by the second frame layer and the center layer; and a test terminal provided on the outer side surface of the container body and used to test the crystal blank. The center layer has at least a first layer and a second layers, and the test terminal is electrically connected to a crystal retaining terminal provided on the bottom surface of the first recess in order to retain the crystal blank through a conductive path provided on an interface between the first and second layers.
