An ink jet recording head includes a recording element substrate and a supporting member. The recording element substrate has an energy generating element that generates energy used for discharging liquid. The supporting member has a plurality of supply paths that are through holes facilitating supplying liquid to the recording element substrate, and supports the recording element substrate. A first protrusion is provided on a surface of the supporting member in contact with adhesive for bonding the recording element substrate, and at each end in the longitudinal direction of each of partition walls formed between the plurality of supply paths. |
