ABSTRACT:
In a surface-mount crystal oscillator, an IC chip having an IC terminal at each of at least four corner portions is housed in a substantially rectangular recess. Circuit terminals to which the IC terminals are fixed via bumps are provided on an inner bottom surface of the recess, and external terminals electrically connected to the circuit terminals are provided at the four corner portions of an opening end surface surrounding the recess. In each of at least three vertices or corners on the inner bottom surface of the recess, an external terminal corresponding to the vertex is formed into an L-shape to be in contact with a longer side and a shorter side of an outer perimeter of the recess, and an exposed part in which the inner bottom surface is exposed is formed between the circuit terminal which is the closest to the vertex and its external terminal.
