<p>PROBLEM TO BE SOLVED: To solve a problem that heat generated by driving a head is not efficiently radiated by a simple structure.SOLUTION: A liquid discharge device includes multiple driving pillars 12A which generate a pressure for discharging droplets. A first wiring member 15 which transmits a driving signal from a drive IC 509 is connected to the driving pillars 12A. The liquid discharge device further includes a second wiring member 16 connected to the first wiring member 15. The second wiring member 16 is a wiring member with a metal shield member. A wiring pattern 151 capable of conducting heat is provided at the first wiring member 15. The wiring pattern 151 of the first wiring member 15 and a metal shield member of the second wiring member 16 are connected by a heat conduction connection pad part 153 so that heat is conducted therebetween.</p> |
