Summary:PROBLEM TO BE SOLVED: To provide a piezo electric element capable of suppressing reduction of an intensity.SOLUTION: A piezo electric element 1 comprises: an external electrode 3 and an internal electrode 7 opposite each other; a piezoelectric layer 11 arranged between the external electrode 3 and the internal electrode 7; and a plurality of through hole conductors 10a that penetrate the piezoelectric layer 11, and is connected to the external electrode 3 and the internal electrode 7. The plurality of through hole conductors 10a is arranged in a matrix form view from a main surface opposite direction.SELECTED DRAWING: Figure 6 【課題】強度の低下を抑制することが可能な圧電素子を提供する。【解決手段】圧電素子１は、互いに対向する外部電極３と内部電極７と、外部電極３と内部電極７との間に配置された圧電体層１１と、圧電体層１１を貫通し、外部電極３と内部電極７とに接続された複数のスルーホール導体１０ａと、を備えている。主面対向方向から見て、複数のスルーホール導体１０ａは、行列状に配列されている。【選択図】図６
