In order to reduce a manufacturing cost of an ink jet type recording head by simplifying a structure of the ink jet type recording head and reducing the number of manufacturing steps thereof, to provide a capacity of an ink pool without increasing a size thereof, to make the freedom of nozzle layout high and to make the freedom of design by reducing a restriction on position and number of ink supply ports, the ink pool to which ink is supplied is formed in a rear surface of a nozzle plate having a front surface formed with a plurality of nozzles and an ink chamber plate is attached to the rear surface of the nozzle plate through discrete partition walls each defining a discrete space communicating with different one of the nozzles.
