Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inkjet printhead capable of establish a dominant stress concentration when solidifying melted ink.SOLUTION: Protrusions 312 are arranged on the inner surface of a channel 300 within an inkjet printhead body to control the size and location of bubble formed in melted solid ink 310. The inkjet printhead includes a member having a first opening and a second opening to enable the melted solid ink 310 to enter the channel 300 from the first opening and flow through the channel 300 to the second opening. Each protrusion 312 establishes a dominant stress concentration in the melted solid ink 310 to regulate the location of bubble formation. 【課題】溶解インクが凝固する際の支配応力を集中させることができるインクジェット記録ヘッドを提供する。【解決手段】インクジェット記録ヘッド本体内のチャネル３００の内面上に突起部３１２を配置し、溶解した固形インク３１０中に発生する気泡の大きさ、および位置を調整する。インクジェット記録ヘッドは、第１の開口および第２の開口を有する部材を備えて、溶解した固形インク３１０が第１の開口からこのチャネル３００に入り、このチャネル３００内を第２の開口まで流れるようにする。突起部３１２は、溶解した固形インク３１０内の支配応力を集中させ、気泡発生位置を規制する。【選択図】図１Ａ
