PROBLEM TO BE SOLVED: To provide a piezoelectric device which can be miniaturized without using a plurality of piezoelectric resonators and can output a free oscillation signal as necessary in generating a plurality of oscillation signals. SOLUTION: In the piezoelectric device, a first rectangle container in which a first piezoelectric resonation element is housed in a first recess portion is placed and fixed on the top surface of a second rectangle container in which a second piezoelectric resonation element is housed in a second recess. The first container is electrically connected to the second container with a conductive joining material, and a circular sealing member surrounding the second recess is provided between the first and second containers outside the conductive joining material.
