Abstract
A liquid discharge head includes a piezoelectric element, a piezoelectric element-formed substrate, a drive IC, and a wiring board which has a first side and a second side intersecting each other. The wiring board has two surfaces including a first surface facing the drive IC and a second surface facing the piezoelectric element-formed substrate. The wiring board includes, on the first surface, a first input terminal for a drive signal to the piezoelectric element, a second input terminal for a control signal, a first wire connected to the first input terminal, and a second wire connected to the second input terminal. The first wire has a first connection terminal. The second wire has a second connection terminal. A distance along the second side from the first side to the first connection terminal is longer than a distance along the second side from the first side to the second connection terminal.
