<p>PROBLEM TO BE SOLVED: To provide a piezoelectric device which secures air tightness, prevents increase in a resistance value of wiring, and secures conduction of the wiring, and to provide a manufacturing method of the piezoelectric device.SOLUTION: A piezoelectric device 100 includes: a base 130; a frame part (a crystal vibration piece 120 with a frame) having a bottom surface joined to one main surface of the base 130 by a joint material 153 and enclosing an outer peripheral part of the one main surface, the frame part in which a bottom surface electrode (an extraction electrode 126A) is formed; and a lid 110. The joint material 153 includes: a conductive joint material 150A; an insulative joint material 151A; and a mixed joint material 152A located between the conductive joint material 150A and the insulative joint material 151A.</p> |
