PROBLEM TO BE SOLVED: To provide a liquid jetting head and a liquid jetting device which do not require the installation of a separate driving source and can easily stir a liquid in a pressure chamber.SOLUTION: A liquid jetting head 2 can jet liquid droplets from a nozzle 29 by filling a pressure chamber 23 communicating with a nozzle 29 with a liquid and imparting a pressure variation to the liquid in the pressure chamber 23. The bottom of the pressure chamber 23 comprises a bottom member 17 and a vibrating plate 16 laminated on the pressure chamber 23 side face of the bottom member and having flexibility. An empty portion 30 dented to the side opposite to the pressure chamber 23 is formed in a part corresponding to the pressure chamber 23 in the bottom member 17, the vibrating plate 16 covers the opening of the empty portion 30 from the pressure chamber 23 side and a hole 27 making the empty portion 30 communicate with the pressure chamber 23 is formed. |
