Abstract
A recording head has a substrate on which a plurality of heat generating elements as recording elements are arranged and a plurality of driving integrated circuits (driving ICs) to drive the plurality of heat generating elements are supported. The recording head comprises wirings which are extended from the heat generating elements and pass through a region on the substrate on which the driving ICs are supported and are connected to the driving ICs; signal series wirings which are arranged on the heat generating element side of the substrate, are closer to the heat generating elements than terminals for the wiring connection, and serially connect the driving ICs; and conductors which are formed in a region on the substrate between the adjacent driving ICs and connect recording current to the ground.
