摘要：
A recording head includes a liquid ejecting outlet, a liquid passage communicating with the ejection outlet, and a heat generating resistor for supplying heat to the liquid in a heat acting portion in the liquid to create a bubble in the liquid passage to eject the liquid through the ejection outlet. A cross-sectional area of the liquid passage increases from the heat acting zone toward the ejection outlet, and this improves performance while also improving head durability.
