ABSTRACT:
An ink jet recording head includes ejection energy generating elements for ejecting ink, flow passages for supplying the ink from an ink supply port to the ejection energy generating elements through a common liquid chamber, a partition wall formed between adjacent two flow passages, a member disposed between the partition wall and the ink supply port, and an opening formed between the partition wall and the member. A flow resistance in the opening from one of the adjacent two flow passages to the other flow passage is different from that in the opening from the other flow passage to the one of the adjacent two flow passages.
