Embodiment Construction

[0017] The sealing step of the liquid jet head according to the present invention will be described with reference to the drawings.

[0018] figure 1 An example of the structure of an inkjet recording head as a liquid ejection head according to the present invention is shown. Figure 2A-2E express figure 1 An example of a method of manufacturing an inkjet recording head as a liquid ejection head according to the present invention in Section 2-2 of .

[0019] Such as Figure 2A As shown in , the support 6 holds a sheet formed of a silicon substrate 5, an ink flow path wall member 8 serving as a liquid flow path wall member, and a contact layer 9 disposed between the substrate and the member. A liquid ejection pressure generating element and bumps 7 serving as electrode terminals for electrically connecting the liquid ejection pressure generating element to the outside are formed on the silicon substrate 5 . In addition, the supporting member 4 integrated with the supporting...

Abstract

A liquid ejection head includes a chip having a liquid ejection pressure generating element and an electrode terminal for electrically connecting the liquid ejection pressure generating element to an external source, an electrical wiring board having a lead wiring to be electrically connected to the electrode terminal, and a lead sealing material for covering an electrical connection portion between the electrode terminal and the lead wiring. The lead sealing material contains an epoxy resin which has an average number of functional groups per molecule of more than two and is solid at 25° C., an acid anhydride curing agent having a polybutadiene backbone, a curing accelerator, and an inorganic filler.

Description

technical field [0001] The present invention relates to a liquid ejection head that ejects a liquid and a method of manufacturing the liquid ejection head, and in particular, to an inkjet recording head that ejects ink onto a recording medium for recording and a method of manufacturing the inkjet recording head. Background technique [0002] A specific example of the liquid ejection head ejecting liquid is an inkjet recording head each applied to an inkjet recording system according to which ink is ejected onto a recording medium so as to perform recording. [0003] Japanese Patent Application Laid-Open No. 2004-351754 has the following description regarding the preparation of an inkjet recording head. First, a plurality of ejection pressure generating elements and electrode terminals for electrically connecting the elements to the outside are provided on a silicon substrate. Then, a resist is patterned to occupy a portion serving as an ink flow path. In addition, ink chan...
