Abstract

The invention provides a liquid jet head and a liquid jet system which can prevent or reduce the chemical influence caused by the used liquid. The liquid jet head is successively laminated with a first flow passage forming part which forms a first flow passage to the nozzle opening, a sealing part which seals the opening of the first flow passage, and a second flow passage forming part which has asecond flow passage for supplying liquid to the first flow passage. The connecting part of the first flow passage and the connecting part of the second flow passage are formed in the density throughthe The sealing part is provided with a diaphragm layer (47) forming one side of the first flow path and a resin layer (c) laminated on the diaphragm layer. At least a part of the inner wall of the communication port is covered by a 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...
