Small low times constitute a high capacity pump fluid pump (101). Fluid pump 101 is composed of a flat portion (51) by the metal plate and the actuator 40. Actuator 40 is a piezoelectric element is attached (42) of the disk-like diaphragm 41 of a disk shape. By being a rectangular wave or sine wave shape is applied to the driving voltage of the actuator 40 it is bent over the periphery from the center of vibration. Actuator 40 has not been a constraining its periphery. Actuator 40 will close the flexural vibration in a state opposite to the flat portion (51). The center or near the center of the flat portion facing the actuator region opposed to the actuator 40 of 51 there is arranged a central vent hole (52).
