Abstract
【解決手段】吐き出されるインクが充填されるインクチャンバがその表面側に形成され、インクチャンバにインクを供給するためのマニホールドがその背面側に形成され、インクチャンバとマニホールドとを連結するインク流路がその表面に並んで形成された基板と、基板上に積層され、インクチャンバからインクが吐き出されるノズルが形成され、ヒータ及びヒータと電気的に連結されてヒータに電流を印加する電極が配置されたノズル板とを備える。これにより、インク流路をインクチャンバと同一平面上で基板の表面に並んで形成することにより、インクの逆流現象による吐き出し不良等を防止してプリントヘッドの性能を向上させ得る。
