PROBLEM TO BE SOLVED: To provide a recording head whereby the number of nozzles in the recording head can be increased at low cost, and a recorder. SOLUTION: Ink introduced through an ink supply hole of a recording head 112 is filled in a common ink channel 20. The ink is filled in a lower pressurizing chamber 12 and an upper pressurizing chamber 13 from the common ink channel 20 passing through ink supply paths 18, 19. An actuator 35 is bent such that the upper pressurizing chamber 13 becomes to be convex and the lower pressurizing chamber 12 becomes to be concave. One actuator 35 can carry out compression or decompression (expansion) of the upper pressurizing chamber 13 and the lower pressurizing chamber 12. By controlling to drive the actuator 35, ink drops are independently ejected from nozzles 10, 11 respectively communicating with the upper pressurizing chamber 13 and the lower pressurizing chamber 12.
