Abstract

The present invention provides a liquid ejection head and a liquid ejection system capable of preventing or reducing chemical effects on a liquid used. This liquid ejection head has a first flow path forming member forming a first flow path leading to a nozzle opening, a sealing member sealing the opening of the first flow path, and a device for supplying water to the first flow path laminated in this order. A second flow path forming member for a second flow path of liquid, a communication portion of the first flow path and a communication portion of the second flow path communicating through a communication port formed on the sealing member, the sealing member It has a diaphragm layer (47) constituting one surface of the first flow channel, and a resin layer (C) laminated on the diaphragm layer, and at least part of the inner wall of the communication port is covered with the resin coating layer (A) , the resin coating layer is composed of a second resin different from the first resin forming the resin layer.

Description

technical field [0001] The present invention relates to a liquid ejection head such as an ink jet recording head and a liquid ejection system. Background technique [0002] As a liquid ejection head that is ejected from a nozzle in the form of liquid droplets by changing the pressure of the liquid in the pressure chamber, there are, for example, ink jet recording heads used in image recording devices such as printers, and color filters such as liquid crystal displays. Production of color material injection heads used in manufacturing, electrode material injection heads used in electrode formation of organic EL (Electro Luminescence) displays, FED (Field Emission Displays), and biochips (biochemical elements) Bioorganic injection heads used in [0003] A recording head, which is a type of liquid ejection head, is constituted by having a continuous liquid flow path from a common ink chamber (common liquid chamber / reservoir) through a pressure chamber to a nozzle, and generati...
