Peizoelectric element and piezoelectric device

A piezoelectric element comprising:

• a vibration portion approximately quadrangular in plan view and comprising a pair of vibration main surfaces;
• a holding portion thicker than the vibration portion, located along at least one edge side of the vibration portion in plan view and integrated with the vibration portion, and comprising a pair of holding main surfaces;
• a pair of excitation electrodes each located on a corresponding one of the pair of vibration main surfaces;
• a pair of mounted electrodes each located on a corresponding one of the pair of holding main surfaces;
• and
• a pair of wiring electrodes each electrically connecting a corresponding one of the pair of excitation electrodes and a corresponding one of the pair of mounted electrodes, wherein
• one of the pair of vibration main surfaces and one of the pair of holding main surfaces are on a same plane,
• another of the pair of holding main surfaces comprises a fixing portion configured to be in contact with an element mounting member,
• the pair of mounted electrodes are located side by side on the fixing portion, and
• an inner peripheral edge of each of the pair of mounted electrodes is an inner side edge and an inner peripheral edge of each of the pair of wiring electrodes is an inner side edge,
• the inner side edge of each of the mounted electrodes and the inner side edge of a corresponding one of the wiring electrodes are connected in a straight line.
