Abstract
The liquid ejection head includes: a liquid flow channel of which at least one wall is constituted by an elastic member; a nozzle which is provided at an end of the liquid flow channel; and a pressure generating device which generates a pressure pulse wave in liquid inside the liquid flow channel. The liquid flow channel and the pressure generating device are composed in such a manner that the pressure pulse wave propagates as a soliton through the liquid in the liquid flow channel.
