Abstract:
A liquid discharge head includes a plurality of pressure generating elements configured to generate pressure to discharge a liquid, a plurality of wirings configured to transmit a drive signal to the plurality of pressure generating elements, respectively, a plurality of integrated circuits configured to drive the plurality of pressure generating elements, respectively, the plurality of integrated circuits being provided on the plurality of wirings, respectively, and a heat sink configured to contact the plurality of integrated circuits to dissipate heat in the plurality of integrated circuits. The heat sink includes a first dissipation part that directly contacts one of the plurality of integrated circuits, and a second dissipating part that contacts another of the plurality of integrated circuits via one of the plurality of wirings.
