PIEZOELECTRIC ELEMENT, ULTRASONIC PROBE, AND ULTRASONIC IMAGING APPARATUS

OZAWA HITOSHI / MINEMOTO TAKASHI / KATO JUNICHI / SAITO TAKAYOSHI

PROBLEM TO BE SOLVED: To provide an ultrasonic probe excellent in sensitivity to ultrasonic waves even when the thickness of a piezoelectric composition is small.SOLUTION: The ultrasonic probe has a piezoelectric element including a piezoelectric composition and an electrode for applying a voltage to the piezoelectric composition. The piezoelectric composition has piezoelectric properties included in a region surrounded by a polyhedron having a predetermined plurality of points as apexes in rectangular coordinates (k, ε, E) with k, ε, and Eas variables.SELECTED DRAWING: Figure 2

【課題】圧電組成物の厚みが小さい場合でも、超音波に対する感度に優れる超音波探触子を提供する。【解決手段】上記超音波探触子は、圧電組成物と、圧電組成物に電圧を印加するための電極とを備えている圧電素子を有する。圧電組成物は、ｋｅｆｆ、ε３３ＳおよびＥｃを変数とする直交座標（ｋｅｆｆ，ε３３Ｓ，Ｅｃ）において所定の複数の点を頂点とする多面体で囲まれる領域に含まれる圧電特性を有する。【選択図】図２
