Fluid path member, liquid discharge head, recording apparatus, and method for manufacturing a flow path member

摘要

In the flow path member for the liquid discharge head, a plurality of plates (4 e, 4 f) in which holes serving as flow paths or grooves serving as flow paths are arranged are laminated via an adhesive layer (18), and the plate The escape groove (17) of the adhesive is arranged on the edge (4e) of the plate (4e) and the edge of the escape groove (17) And has a protruding first convex portion (17 a). The first convex portion (17 a) contacts the laminated plate (4 f) to suppress the adhesive layer (18) from becoming too thin, thereby suppressing the adhesive from protruding into the flow path.
