Description
(実施形態1)
図1は、本発明の実施形態1に係る液体噴射ヘッドの一例であるインクジェット式記録ヘッドの概略構成を示す分解斜視図であり、図2は、図1の平面図及びそのA−A′断面図である。
以上、上述した実施形態1では、液体噴射ヘッドの一例としてインクジェット式記録ヘッドIを挙げて説明したが、本発明は広く液体噴射ヘッド全般を対象としたものであり、インク以外の液体を噴射する液体噴射ヘッドにも勿論適用することができる。その他の液体噴射ヘッドとしては、例えば、プリンタ等の画像記録装置に用いられる各種の記録ヘッド、液晶ディスプレー等のカラーフィルタの製造に用いられる色材噴射ヘッド、有機ELディスプレー、FED(電界放出ディスプレー)等の電極形成に用いられる電極材料噴射ヘッド、バイオchip製造に用いられる生体有機物噴射ヘッド等が挙げられる。
