Abstract
In a surface-mount type crystal oscillator according to the invention, a part of side surfaces of a lower cavity are formed into bulging space portions bulging into separating areas between adjacent ones of a plurality of terminal electrodes provided around the lower cavity. By accommodating an IC chip and an electronic device in the lower cavity including the bulging space portions, the crystal oscillator can be miniaturized without affecting the size of the plurality of terminal electrodes.
