Abstract
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.

An ink jet recording head comprising:
- a recording element substrate having an energy generating element that generates energy used for discharging liquid;
- and
- a supporting member having a plurality of supply paths that are through holes facilitating supplying liquid to the recording element substrate, the supporting member supporting the recording element substrate,
- wherein 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.
A method for manufacturing an ink jet recording head including:
- a recording element substrate having an energy generating element that generates energy used for discharging liquid;
- and a supporting member having a plurality of supply paths that are through holes for supplying liquid to the recording element substrate, the supporting member supporting the recording element substrate, the method comprising:
- preparing the supporting member in which a first protrusion is provided on a surface of the supporting member and at each end in the longitudinal direction of each of partition walls formed between the plurality of supply paths;
- applying an adhesive to the surface of the supporting member;
- and
- bonding the supporting member and the recording element substrate.
