図2は、本発明の第一実施形態に係る液体噴射ヘッドの製造方法を表す工程図である。本実施形態は、シェブロンタイプの液体噴射ヘッドの製造方法である。図1と異なる部分は、溝形成工程S2の前に樹脂膜パターン形成工程S7が挿入され、電極材料堆積工程S3の後に樹脂膜剥離工程S8が挿入されている。これは、リフトオフ法により電極を形成するためである。更に、第二ベース基板接合工程S6の後にノズルプレート接合工程S9及びフレキシブル基板接合工程S10を備えている。以下、図3、図4及び図5を用いて具体的に説明する。
図6は、本発明の第二実施形態に係る液体噴射ヘッド1の分解斜視図である。本発明の液体噴射ヘッド1の製造方法により形成した。同一の部分又は同一の機能を有する部分には同一の符号を付している。
図7は、本発明の第三実施形態に係る液体噴射装置50の模式的な斜視図である。本液体噴射装置50は、上記第一又は第二実施形態で説明した液体噴射ヘッド1を使用している。液体噴射装置50は、液体噴射ヘッド1、1’を往復移動させる移動機構63と、液体噴射ヘッド1、1’に液体を供給する液体供給管53、53’と、液体供給管53、53’に液体を供給する液体タンク51、51’を備えている。各液体噴射ヘッド1、1’は、液体を吐出させる吐出チャンネルと、この吐出チャンネルに液体を供給する液体供給室と、液体供給室に液体を供給する図示しない圧力緩衝器を備えている。
