Liquid jet recording head and liquid jet recording apparatus having same

摘要

A liquid jet recording head (400) includes a heat generating element (408); a heat acting zone (406) in which heat generated by the heat generating device acts on liquid; a liquid feeding passage (405) adjacent to the heat acting zone having a liquid supply opening for supplying liquid to the heat acting zone (406); a liquid ejection passage (407) adjacent the heat acting zone and having an orifice (402) through which the liquid is ejected; wherein a center line (410) passing through the center of the liquid supply opening along a direction of the liquid supply from the liquid supply passage to the heat acting zone is directly across a wall constituting the liquid ejection passage.
