Abstract
A nozzle plate for an ink-jet head used in an ink-jet type recorder, comprising a flat plate member which defines an ink blow-out surface on one main surface thereof and has a plurality of ink blow-out nozzles penetrating at predetermined positions, wherein said ink blow-out surface and portions on the inner surfaces of said ink blow-out nozzles neighboring said ink blow-out surface, have, at least partly, an ink-repelling layer of a fluorine-contained resin-containing electrolytic or non-electrolytic composite plating. Upon forming a particular ink-repelling layer on the nozzle plate, it is possible to prevent the ink from staying adhered on the peripheries of the nozzles after the ink droplets are blown out from the nozzles, permitting the ink droplets to fly stably toward the recording medium.
