ABSTRACT:
An ink jet recording head includes an ejection outlet for ejecting ink; an energy generating element, provided on a silicon substrate, for generating energy for ejecting the ink from the ejection outlet; an ink flow passage, provided correspondingly to the energy generating element, communicating with the ejection outlet; a through hole passing through the silicon substrate; and an ink supply port for supplying the ink supplied into the through hole to the ink flow passage. The ink supply port is formed with an extended member which contacts a bottom of a flow passage wall constituting the ink flow passage and extends into an opening of the through hole.
