Abstract
A pressure generating member applies a pressure to an ink, the member having a symmetric configuration and including a buckling body. The buckling body may include a radially extending ribbed portion on its upper surface and no buckling layer beneath it. A heater layer is interposed between insulating layers for heating the buckling body, the buckling body having its peripheral edge portion fixed on a substrate. A center portion of the buckling body is buckled by being heated. An orifice plate is arranged so as to cover the pressure generating member with interposition of a gap defining a cavity for the ink. The orifice plate is provided with a nozzle serving as an ink discharge outlet located in a portion of the orifice plate opposite to the pressure generating member.
