Abstract: The present invention aims to provide a liquid discharge head capable of reducing the possibility that ink intrudes into the interior thereof. The liquid discharge head includes a head body which has a plurality of discharge holes, a plurality of pressurizing chambers communicating with the discharge holes, and piezoelectric bodies disposed correspondingly to the pressurizing chambers, a flexible wiring board electrically connected to the piezoelectric bodies, a first member having a hole disposed on the head body, and a second member disposed on the first member. A part of the second member is disposed so as to cover the hole in a plan view. The flexible wiring board is passed through the hole and is led out from between the first member and the second member.
