Piezoelectric element and piezoelectric sensor |
| abstract |
This piezoelectric element comprises a layered body and an external electrode. In the layered body, a plurality of piezoelectric bodies and internal electrodes are laminated. The external electrode is positioned on a side surface of the layered body and is connected to the internal electrodes. The layered body has an active region sandwiched between internal electrodes having different polarities, and an inactive region sandwiched between internal electrodes having the same polarity. The internal electrodes contain Ag and Pd as primary components. An active section of the internal electrodes located in the active region is a first section. An inactive section of the internal electrodes located in the inactive region has a second section with a higher Pd content than the first section. The first section has a higher Ag content than the second section. |
