Abstract
A liquid jet head includes a nozzle member having plural nozzles for jetting a liquid therefrom, a flow path member forming at least a part of a liquid chamber communicating with each of the plural nozzles, and a pressure generating part for generating pressure that is applied to the liquid inside the liquid chamber. The nozzle member and the flow path member are each formed by a metal material. The metal material of the nozzle member has substantially the same composition as the metal material of the flow path member. The metal material of the nozzle member includes crystal particles having an average particle diameter which is less than that of the crystal particles included in the metal material of the flow path member.
