In an ink-jet recording head using piezoelectric members, unwanted ejection of an ink material due to cross-talk is prevented. A head 10 comprises a channel plate 16 provided with a plurality of nozzles 28 and ink cavities 26, respectively, a diaphragm 18 adapted to cover the ink cavities, a vibration plate 20 with a plurality of piezoelectric members opposed to respective ink cavities through the diaphragm and a base plate 22 for supporting the piezoelectric members. The base plate 22 is formed such that a value of the elastic modulus multiplied by the thickness thereof is about 9.0x103 (kgf/mm) or more.
