Provided is an inkjet head with which the wiring spacing can be widened without enlarging the inkjet head circuit board and which is capable of stable connections when connecting the circuit board with a connection substrate using pressurization. An inkjet head, which is provided with multiple nozzles for discharging ink, multiple piezoelectric elements that serve as driving sources for discharging the ink from the nozzles, and a circuit board (50) with wiring for supplying electricity to the multiple piezoelectric elements, is characterized: in having connection terminals (501), which are provided on both surfaces of the circuit board (50) for connecting connection substrates (4) using pressurization; and in the connection terminals (501) being provided at positions that overlie each other on the front surface and back surface of the circuit board (50). |
