ABSTRACT:
A cavity plate of an ink-jet head is formed by stacking a clad plate on a manifold plate. The clad plate is formed by unitarily bonding a first layer and a second layer, which are made of different materials. Pressure chambers and communicating holes to the pressure chambers are formed in the first and second layers, respectively. Each of the first and second layers is etched using an etching agent that is able to only one of the layers to form therein the pressure chambers or the communicating holes. Thus, the pressure chambers and the communicating holes are formed with high precision in depth. In addition, the cavity plate including the clad plate with a predetermined thickness is easy to handle when manufactured into an ink-jet head.
