Abstract
A liquid-discharging head includes a pressure-generating element configured to be actuated to apply pressure on liquid in a pressure chamber from which the liquid is discharged through a nozzle, an actuation controller configured to control actuation of the pressure-generating element, a heat-releasing member configured to contact the actuation controller, and a cover member configured to cover the actuation controller and part of the heat-releasing member. The heat-releasing member includes a first heat-releasing member and a second heat-releasing member. The first heat-releasing member is arranged outside the cover member and has a surface exposed to external air. The second heat-releasing member is arranged inside the cover member and has a first end portion to contact the actuation controller. The first heat-releasing member and the second heat-releasing member are arranged to contact each other.
