PROBLEM TO BE SOLVED: To provide a technique capable of improving the structural strength of a pressure chamber.SOLUTION: A liquid discharge head 1 is formed by stacking at least a channel substrate 30 having a communication hole 31 communicating with a nozzle 81 and a pressure chamber substrate 10 having a space to form a pressure chamber 12, and includes an actuator 2 having an active part 4 sandwiched by electrodes 21 and 22 for pressing the pressure chamber 12. The pressure chamber substrate 10 has a first space S1 positioned in a region corresponding to the active part 4 of the space, and a second space S2 positioned closer to the nozzle 81 than the first space S1 to communicate with the first space S1. The communication hole 31 is adjacent to the second space S2 and is not adjacent to the first space S1. |
