| Abstract | To provide a piezoelectric element capable of improving the reliability of electrical connection at a conductor.SOLUTION: A piezoelectric element PD1 comprises: an element body 1; an external electrode arranged on an outer surface of the element body 1; and an internal electrode connected with the external electrode and arranged in the element body 1. The internal electrode has an internal conductor 31 and an internal conductor 32 opposed to each other. The internal conductor 32 includes a conductor portion 32b extending in a first direction D1 and connected with the internal conductor 31. The conductor portion 32b is formed with a cavity 50.SELECTED DRAWING: Figure 5
【課題】導体での電気的な接続の信頼性を向上する圧電素子を提供する。【解決手段】圧電素子ＰＤ１は、素体１と、素体１の外表面に配置されている外部電極と、外部電極に接続されていると共に、素体１内に配置されている内部電極と、を備えている。内部電極は、互いに対向している内部導体３１と内部導体３２とを有している。内部導体３２は、第一方向Ｄ１に延在していると共に内部導体３１に接続されている導体部分３２ｂを含んでいる。導体部分３２ｂには、空洞５０が形成されている。【選択図】図５ |
