Description
かかる第1の態様では、流路形成基板の厚さを相対的に変化させることで、圧電素子保持部に対向する領域の流路形成基板の剛性を端部近傍の剛性よりも高くしているため、ノズルプレートを接合する際に流路形成基板が圧電素子保持部側に変形するのを防止でき、流路形成基板とノズルプレートとを良好に接合することができる。
かかる第2の態様では、流路形成基板にノズル連通板を接合することで、ノズルプレートを接合する際の流路形成基板の変形をより確実に防止できる。
(実施形態1)
図1は、実施形態1に係るインクジェット式記録ヘッドの分解斜視図であり、図2は、図1の概略平面図及びそのA−A’断面図であり、図3は、図2のB−B’断面図である。図示するように、流路形成基板10は、本実施形態では面方位(110)のシリコン単結晶基板からなり、その両面には予め熱酸化により形成した二酸化シリコンからなる、厚さ1〜2μmの弾性膜50が設けられている。
一方、流路形成基板10の開口面側には、各圧力発生室12のインク供給路14とは反対側で連通するノズル開口21が穿設されたノズルプレート20が接着剤や熱溶着フィルム等を介して固着されている。
以上、本発明の実施形態について説明したが、勿論、本発明は上述の実施形態に限定されるものではない。例えば、上述の実施形態では、実質的に圧電素子保持部31に対向する領域の流路形成基板10の表面のみが曲面(球面)となるように研磨した例を説明したが、流路形成基板10の表面形状はこれに限定されず、例えば、図7に示すように、流路形成基板10のノズルプレート20との接合面全体が曲面となっていてもよい。
