Manufacturing method of piezoelectric actuator for a liquid ejecting head and an image forming apparatus |
| 摘要 |
A piezoelectric actuator is disclosed. The piezoelectric actuator (20) includes a base member (13) and three or more piezoelectric element members (12) in which plural piezoelectric elements (12a) are formed by slits (30). The three or more piezoelectric element members (12) are arrayed in a line on the base member (13) and a gap (31) is formed at the connection position between two adjacent piezoelectric element members (12). |
