Liquid discharge head and method of producing liquid discharge head

Abstract

There is provided a liquid discharge head including: a channel substrate including a pressure chamber; a support substrate having a through hole; a piezoelectric element disposed between the channel substrate and the support substrate in a thickness direction of the channel substrate; a drive section disposed on a surface of the support substrate on a side opposite to the piezoelectric element; a trace passing through the through hole of the support substrate, extending on the support substrate toward the drive section, and connected to the piezoelectric element and the drive section; and a reservoir member including a channel communicating with the pressure chamber, and joined to the surface of the support substrate with adhesive. A protrusion or a recess is provided on the surface of the support substrate on the side opposite to the piezoelectric element at a position between the trace and the channel.
