Functional thin film, piezoelectric device, ink jet recording head, printer, method of producing piezoelectric device, and method of producing ink jet recording head |
摘要 |
The present invention is to produce a piezoelectric device with which the number of production processes can be reduced and reliability can be improved. A piezoelectric device (40) comprises one or more piezoelectric thin film layers (43) and 2 or more electrode layers (42 and 44). Mixed layers (512, 523, and 534) where the components of adjacent layers are mixed are formed between the respective layers.
