Abstract:
1. A method of manufacturing a liquid jet head having a liquid discharge port for discharging liquid, a liquid flow path communicating with the liquid discharge port and a liquid discharge energy generation element provided in a place corresponding to the liquid flow path to generate energy used for discharging the liquid, said method comprising: a step of forming on a substrate a first coat resin layer on which the liquid discharge port is provided; a step of forming a liquid flow path pattern with a soluble resin in the first coat resin layer; a step of forming a second coat resin layer which constitutes a liquid flow path wall and a vibration plate, the liquid flow path wall being a wall covering the liquid flow path pattern; a step of disposing the liquid discharge energy generation element in a place corresponding to the liquid flow path; a step of forming a bond layer constituting a bond portion with respect to the liquid discharge energy generation element on the second coat resin layer; a step of separating and removing the substrate; and a step of removing the liquid flow path pattern to form the liquid flow path.
