Abstract
A liquid-jet recording head comprises an ejection opening for ejecting liquid, a liquid path communicating to the ejection opening and a substrate having an energy-generating element provided in correspondence with the ejection opening. The substrate is combined with a heat-capacity member and the heat accumulated in the substrate is efficiently released through the heat-capacity member.
