摘要：Problem to be solved: to promote heat dissipation from the driving device tothe wiring, and to suppress heat transfer to the liquid in the pressure chamber and to thepiezoelectric element. The cover member 23 joined to the flow path substrate 21covering the plurality of piezoelectric elements 31 has a plurality of wall portions 62
arranged in the scanning direction.The plurality of lead wires 42 drawn out from theplurality of piezoelectric elements 31 pass through the junction region between the wallportion 62 and the flow path substrate 21 and extend to the outside of the covermember 23.The outer wall portion 62A of the plurality of wall portions 62 of the covermember 23 is larger than the wall portions 62b and 62c located on the other side thanthe wall portion 62A, and the junction area to the flow path substrate 21 is large.Diagram
