摘要： A plate assembly for ink-jet-type printing head assures a smooth ink flow and prohibits fluctuation in ink discharge quantity and speed to realize a satisfactory printing quality. A plurality of plates are bonded each other by using a thermoplastic-resin intermediate sheet having a shape corresponding to the opposite surfaces of adjacent plates. The intermediate sheet has ink passage openings of a dimension which includes a reference contour which is an axial projection of a corresponding opening in the plate. The ink passage opening in the intermediate sheet has a periphery which is set-back from the reference contour by a predetermined amount in the reference direction connecting adjacent ink passage openings, and by an increased amount in other directions. The plates and the intermediate sheet are superimposed one above the other and subsequently heated under pressure to form an integral plate assembly.
