Abstract
A method for producing an ink jet recording head having a plurality of recording element substrates each including a recording element for generating energy to be used for ink discharge and an electrode portion connected to the recording element, a wiring substrate provided with an electrode terminal to be electrically connected with the electrode portion of the plural recording element substrates and adapted to transmit an electrical pulse for ink discharge to the recording element, and an element substrate support member for supporting the plural recording element substrates, comprises a step of causing the plural recording element substrates to be supported on the element substrate support member, and a step of thereafter executing metal—metal bonding between the electrode portion of the plural recording element substrates and the electrode terminal of the wiring substrate.
