An ink jet recording head capable of separating or coupling ink tanks from or with the head comprises a recording device substrate having a plurality of recording devices thereon for discharging ink, a wiring device for giving electrical recording signals to the recording device substrate, an ink supply member for supplying ink to the recording device substrate, and a filter member for removing dust particles or the like in ink. This recording unit is provided with all the functions of discharging ink, and coupled with a holder member having only the function of holding and fixing ink tanks. With the structure thus arranged, it becomes unnecessary to connect ink supply paths as in the conventional art, hence eliminating the provision of sealing members. The number of parts is made smaller, while making it possible to carry out inspection of heads only in accordance with the recording units, which significantly contributes to simplifying manufacture and providing highly reliable heads at lower costs.
