摘要 |
Individual electrodes each substantially shaped like a parallelogram are arranged on a piezoelectric sheet in an actuator unit. A land portion is electrically connected to one of acute-angled portions of each individual electrode. Each land portion is disposed between other two adjacent individual electrodes. A C-shaped groove portion is formed around each land portion so as to pierce the piezoelectric sheet along the outer shape of the land portion.
