ABSTRACT:
An inkjet recording head having a head main unit that includes a substrate, a vibration plate, a partition and a top plate, which are integrally assembled as a single unit, a first reinforcing plate fixed to the substrate, and a second reinforcing plate fixed to the top plate. The vibration plate is made of a piezoelectric material. The partition affixed to the vibration plate comprises a thin metal or synthetic resin film. The top plate affixed to the partition has multiple groove-shaped concave areas, which are used as ink cavities, on its surface facing the partition. The first reinforcing plate and the second reinforcing plate are fixed on either side of the head main unit and sandwich the head main unit for reinforcing the substrate and the top plate. Thus, when the piezoelectric members are deformed, accompanying deformation of neighboring piezoelectric members via the substrate or accompanying deformation of the top plate can be mostly prevented and crosstalk can be reduced to a level at which it does not negatively affect image quality.
