Title:
LIQUID EJECTION HEAD, LIQUID EJECTION DEVICE, AND MANUFACTURING METHOD FOR LIQUID EJECTION HEAD
Document Type and Number:
Japanese Patent JP2023161162
Kind Code:
A
Abstract:
To provide a liquid ejection head which makes high precision and nozzle plate deformation inhibition compatible and to provide a manufacturing method for the same.SOLUTION: A liquid ejection head has: a nozzle plate provided with an ejection port for ejecting a liquid; a flow-path formation member adjacent to the nozzle plate and provided with a pressure chamber connected to the ejection port via a nozzle; and an energy generation element configured to generate energy for ejecting the liquid into the pressure chamber; wherein the nozzle plate has a resin layer and a deformation inhibition layer whose Young's modulus is 50 GPa or more.SELECTED DRAWING: Figure 1
