<p>PURPOSE: A liquid injection head and a liquid injection device are provided to vary discharging property by preventing the deviation of a liquid discharge velocity. CONSTITUTION: A liquid injection head comprises an actuator(2), a fluid path member(3) and a first buffer member(4). Long grooves are arranged in the surface of the substrate of actuator. The actuator discharges liquid from the nozzle which is connected with in the long groove. The fluid path member supplies liquid to a plurality of grooves of actuator. The first buffer member is inserted between the actuator and the fluid path member. The first buffer member interlinks the actuator and the fluid path member. The rubber member is used as a buffer member.</p> |
