Multilayer piezoelectric devices and method of producing the same |
摘要 |
A multilayer piezoelectric device has a laminated body 1 having piezoelectric layers 2 laminated in the direction of a given axis "A" and internal electrode layers 4, 5 each disposed between two respective neighboring piezoelectric layers2. The device further has a underlying layer 3 disposed on a side of the laminated body 1 and electrically connected to the internal electrode layers 4, 5, a first conductive reinforcing layer 10 joined to the underlying layer 3, a second conductive reinforcing layer 11 joined to the first conductive reinforcing layer 10, and a conductive joining material 9 joining the underlying layer 3 to the first conductive reinforcing layer 10. The second conductive reinforcing layer 11 is not directly joined by means of the conductive joining material 9. |
