Abstract
A piezoelectric actuator includes a first active portion interposed by an individual electrodes and a first constant electric potential electrode and a second active portion interposed by the individual electrode and a second constant electric potential electrode, and a wiring structure is provided with a wiring board and driver IC. The wiring board is provided with individual lines, a power line, a ground line, a first and second constant electric potential lines, a first short circuit line for short-circuiting the power line and the first constant electric potential line, and a second short circuit line for short-circuiting the ground line and the second constant electric potential line. Accordingly, a liquid droplet discharge head, which is capable of suppressing the crosstalk, is provided. The liquid droplet discharge head has the wiring structure suitable for the head.
