Abstract

A liquid discharge head (1) includes: a substrate component (10) including: a nozzle (24) to discharge a liquid; a channel (21a, 21b) communicating with the nozzle (24); and a frame (5) bonded to the substrate component with an adhesive in a lamination direction, the frame including a communicating portion (20a, 20b) communicating with the channel. The frame (5) and the substrate component have: a bonding region (9a) in which the frame (5) and the substrate component (10) are bonded with the adhesive; and a non-bonding region (9b) in which the frame (5) and the substrate component (10) are not bonded with the adhesive. The bonding region (9a) has: a first bonding region around the communicating portion (20a, 20b) of the frame (5); and a second bonding region at both end portions of the frame (5) in a longitudinal direction of the frame orthogonal to the lamination direction.
