Abstract
An actuator for the print head of an ink jet printer is fitted to the ink channels of the head. The actuator includes an active layer and a restraining layer. One side of the active layer faces the ink channels. The active layer can deform with a drive voltage applied to it. The restraining layer is provided on the other side of the active layer, and cannot be activated with a drive voltage. The restraining layer restrains the active layer from deforming. It is possible to integrally form the active and restraining layers by stacking green sheets and calcining the stacked sheets at the same time. This makes it possible to provide an actuator simple in structure and low-cost.
