摘要： A liquid jet recording head includes a plurality of ejection outlets through which droplets of liquid are ejected by thermal energy, a plurality of liquid passages communicating with the ejection outlets to supply the liquid, a plurality of supply inlets for supplying the liquid to the passages and a plurality of electro-thermal transducers provided for the respective ejection outlets to produce the thermal energy. Each of the electro-thermal transducers has a heating surface, on the bottom of a corresponding passage, for heating the liquid, and the width of each passage measured in the direction in which the passages are arranged is a maximum at a position between an end of the electro-thermal transducer element near the ejection outlet and an end thereof near the supply inlet, and the width decreases both toward the ejection outlet and toward the supply inlet. This allows the bubble created in the passage by the transducer to expand freely and provides energy-efficient droplet ejection.
