ABSTRACT:
Disclosed is an inkjet printing head which ejects ink in response to generation a bubble in the ink accompanying the action of heat from a heater, and which preferably allows ejection energy to be effectively used, and desired attachment accuracy of a movable valve to be secured and maintained. To this end, employed is a two-body structure formed of a substrate including the heater; and a valve retaining member having the movable valve. Then, the effective use of ejection energy is achieved by appropriately selecting the shape and dimensions of the movable valve. Furthermore, the desired attachment accuracy is secured and maintained by attaching the valve retaining member to the substrate by applying a photolithography process without using an adhesive agent.
