PROBLEM TO BE SOLVED: To highly densely arrange nozzle openings, facilitate work and assembly of component parts constituting a recording head and improve the injection characteristic of an ink droplet. SOLUTION: An ink passage is formed of a first plate having a nozzle opening train formed by arranging a plurality of nozzle openings and communication passages having one ends communicating individually to the nozzle openings, arranged in two rows to face each other with the nozzle opening train interposed between, inclined with a predetermined angle to the direction vertical to the nozzle opening train and crossed with each other at the nozzle opening side, a second plate having a pressure generation chamber connected separately to the other end of the communication passage and arranged in two rows to face each other with the nozzle opening train interposed between, a restrictor which supplies ink to this pressure generation chamber separately and a common ink passage communicating with the restrictor and a third plate having a vibrating plate for sealing the pressure generation chamber.
