ABSTRACT:
A manufacturing method of a liquid jet head comprises the following steps of forming a piezoelectric member which generates a discharge pressure for discharging a liquid on a substrate, disposing a vibration plate on the piezoelectric member, forming a liquid flow path pattern containing a soluble resin on the vibration plate, forming a coat layer containing a resin constituting a wall of the liquid flow path on the liquid flow path pattern, removing the liquid flow path pattern to form the liquid flow path, removing the substrate, and patterning the piezoelectric member in accordance with the liquid flow path.
