Laminate piezoelectric element has multiple laminate structures connected using joining layers to satisfy specific relations including thickness of laminate structure and thickness of joining layer

摘要

The piezoelectric element (10) has multiple laminate structures (11) connected using joining layers (19) to satisfy specific relations including thickness of the laminate structure, thickness of joining layer, Young's moduli of laminate structure and material included in joining layer, number of laminate structures, number of joining layers, and cross-sectional areas of laminate structure and joining layer. An independent claim is also included for manufacturing method of laminate piezoelectric element.
