Abstract
A surface mount type crystal oscillator is provided with: a container body having a bottom plate layer and a frame wall layer which has an opening, the frame wall layer being laminated on the bottom plate layer wherein a recess of the container body is formed by the opening; a crystal blank housed inside the recess; and an IC chip in which an oscillation circuit that uses the crystal blank is integrated. The IC chip has IC terminals used for external connections on one principal surface of the IC chip and is secured to the bottom plate layer. The IC chip is secured to the bottom plate layer by way of an anisotropic conductive material such that the one principal surface of the IC chip confronts the bottom plate layer.
