<p>PROBLEM TO BE SOLVED: To provide a liquid jet head and A liquid jet device capable of preventing detachment of a nozzle plate joined to a flow channel formation substrate.SOLUTION: A liquid jet head is provided with: a plurality of head bodies 200 having a nozzle plate 207 on which plural nozzles 206 are bored; a flow channel formation substrate 201 on which a plurality of pressure generation chambers 202 communicating with a nozzle 206 and a manifold 205 communicating with the plurality of pressure generation chambers 202 are formed, and pressure generation means 209 imparting a pressure for jetting liquid droplets to the pressure generation chambers 202; and a fixed plate 300 which has an exposure port 301 from which the nozzle 206 is exposed and on which each head body 200 is positioned and fixed. When the edge part of the exposure port 301 formed on the fixed plate 300 is positioned in a region facing the manifold 205, a recess 305 with the edge part of the exposure port 301 facing the manifold 205 made to hollow is provided on the surface of the fixed plate 300 on the side of the nozzle plate 207.</p> |
