Abstract:
An ink jet recording head comprising:a recording element substrate having a heat generating element for generating thermal energy to discharge a recording liquid, a first supply port provided on a surface opposed to a surface on which said heat generating element is provided to supply the recording liquid to a region where said heat generating element is located and an electrically connected terminal provided on said surface on which said heat generating element is provided;a print wiring substrate connected to said electrically connected terminal of said recording element substrate to apply an electrical pulse for discharging the recording liquid to said heat generating element;a support member having a second supply port for supplying the recording liquid to said recording element substrate and supporting said recording element substrate so that said first supply port corresponds to said second supply port; anda frame member having an opening larger than said recording element substrate and smaller than said supporting member and joined to said supporting member so that said recording element substrate is located in said opening to hold said print wiring substrate,wherein heat generated by driving said heat generating element is dissipated by said supporting member and said frame member.
