Abstract
A vibration device includes a semiconductor device, a first electrode and a second electrode located in a first surface of the semiconductor device, a vibration element, a third electrode and a fourth electrode located in a first surface of the vibration element, a first connection section that connects the first electrode and the third electrode, and a second connection section that connects the second electrode and the fourth electrode. The semiconductor device and the vibration element have mutually different thermal expansion coefficients. The vibration element has a coupling section located between the third electrode and the fourth electrode, and the coupling section has at least one bend section located between the third electrode and the fourth electrode.
