PROBLEM TO BE SOLVED: To provide a liquid spray head excellent in printing stability and a liquid spray device.SOLUTION: The liquid spray head comprises: an actuator plate having a channel row in which discharge channels are arrayed parallely in a X-direction; a cover plate which has an inlet-side common ink chamber collectively to be communicated with the discharge channels at one end part in a Y-direction and an outlet-side common ink chamber that is collectively communicated with the discharge channels at the other end part in the Y-direction and is laminated on the actuator plate; and a flow path member 54 that is laminated on the cover plate and is long in the X-direction. The flow-path member 54 has an inlet-side pressure buffering portion 93 that is communicated with the inside of the inlet-side common ink chamber and can be bent and deformed, and an outlet-side pressure buffering portion 99 that is communicated with the inside of the outlet-side common ink chamber and can be bent and deformed, where the respective pressure buffering portions 93 and 99 are arrayed parallely in the X-direction.SELECTED DRAWING: Figure 8 |
