摘要：
Described is an ink jet recording head comprising a piezoelectric vibration element (12) which is abutted against a vibration plate (6) by displacing a central point C1 of the piezoelectric vibration element (12) by Δd toward a nozzle opening (2) from a central point C2 of a length L of an effective displacement region on the vibration plate (6), whereby the displacement of the piezoelectric vibration element (12) is transmitted to ink in the vicinity of the nozzle opening (2) efficiently.
