PROBLEM TO BE SOLVED: To provide a simple-structure and low-cost elastic member which is compact and can effectuate the function of a pressure adjustment chamber to the maximum in the pressure adjustment chamber that uses the elastic deformation member prepared for adjusting a gas pressure in a container, and to provide a recording head which has the pressure adjustment chamber using the elastic member, and an inkjet recorder which has the recording head. SOLUTION: The pressure adjustment chamber which adjusts the gas pressure in the container has at least one elastic deformation member whose capacity is changeable in accordance with the gas pressure. The deformation member shape includes one opening of an almost circular shape and nearly flat two surfaces on the periphery in a state before deformed. The two surfaces link each other in a nearly symmetric arrangement via a curved surface part at a tip of the opposite side to the opening in the elastic deformation member. The pressure adjustment chamber uses the elastic deformation member. The pressure adjustment chamber is equipped with a posture control rib to be located at nearly the center of the elastic deformation member from an air hole which communicates with the pressure adjustment chamber.
