Abstract

A liquid jet recording head includes a plurality of ejection outlets through which a droplet of liquid is ejected by thermal energy; a plurality of liquid passages communicating with the ejection outlets to supply the liquid; a plurality of supply inlet for supplying the liquid to the passages; a plurality of electro-thermal transducers provided for the respective ejection outlets to produce the thermal energy; wherein each of said electro-thermal transducers has a heating surface for heating the liquid on the bottom of said passage, characterized in that a width of the passage measured in the direction in which the passages are arranged is maximum at a position between an end of said electro-thermal transducer element near the ejection outlet and an end thereof near the supply inlet, and that the width reduces toward the ejection outlet and toward the supply inlet. <IMAGE>
