摘要：
An ink jet recording head which can compensate for shortage of mechanical strength of an ink reservoir by preventing the piezoelectric film on an ink reservoir from cracking or being broken due to the vibration of a piezoelectric film or flowing or mechanical vibration of ink. The ink reservoir has at least two plane orientations at its bottom and is given different depths.
