An ink-jet head includes a passage unit, a piezoelectric actuator, a first wire member, and a second wire member. The first wire member is connected to the piezoelectric actuator and has a driver IC. The second wire member is connected to the first wire member and has wires. The first wire member includes signal wires, the driver IC, a circuit component that electrically connects two or more of the signal wires, and first contacts connected to the respective signal wires. The second wire member includes the wires, and second contacts connected to the respective wires. The corresponding first and second contacts are connected to each other at and around a portion where the first wire member and the second wire member overlap. The circuit component is disposed near any of the first contacts. All of the first and second contacts, and the circuit component are covered with an insulating tape.
