| titleOfInvention | Piezoelectric drive device, robot, pump, and method of manufacturing piezoelectric drive device |
| abstract | An object of the present invention is to provide a piezoelectric driving device in which a portion in contact with a driven body has high bonding strength with respect to a diaphragm, and a method for manufacturing such a piezoelectric driving device. A piezoelectric driving device according to the present invention includes a piezoelectric element including a piezoelectric body, and a plate-shaped diaphragm 30 on which the piezoelectric element is disposed. The vibration plate 30 includes a portion that contacts the driven body, and includes a first region 20a that includes a sintered body of the first metal oxide, and a sintered body of the second metal oxide that is different from the first metal oxide. A second region 30a including the second region 30a, and a joint portion 30b provided between the first region 20a and the second region 30a and including a solid solution of the first metal oxide and the second metal oxide.
