Abstract
A cavity plate is constructed by laminating, using an adhesive, a plurality of thin plates with ink passages, such as pressure chambers and through holes. In the periphery of the ink passages, escape grooves and holes communicating with the escape grooves are formed such that the remaining adhesive is guided into the escape grooves without entering the ink passages and that air trapped in the adhesive is discharged through the escape holes to the outside. Accordingly, a plurality of thin plates are firmly bonded to each other by a layer of adhesive, while the ink passages remain intact to allow a good flow of ink.
