Abstract: PURPOSE:To perform uniform bonding without leakage of ink which flows in a passageway by providing a flush plane without cutter steps by a method wherein that plane of the same height adjacent to the flow passage of polymer base plate, which makes one round around said passageway, in a continuous form without a step is used as a bonding plane. CONSTITUTION:On a flow passage groove surface of a head base plate 1, a thin plate 8 made of polymer is bonded by a solvent-welding, thermal-welding, and the like, and thereby a sealed flow passage is formed. At this time, bonding is performed by selecting as a bonding surface 9 only the plane with the same height, turning one round around the flow passageway continuously without step. For the manufacturing of the head base plate 1, an injection blow molding is employed, however, when a milling process is employed for mold in the bonding surface, since the plane to be used is of the same continuous height, a proper size of slits are provided. By this process, the working of the surface is performed by using one milling cutter. Thereby there exits no generation of step difference caused by the overlapping of cutters or the replacement thereof, and the surface of uniform height can be realized.
