An ink chamber plate is connected to the piezoelectric ceramic plate and has an ink chamber for supplying ink from the ink storing device to the grooves. A base plate is connected to a side of the ink chamber plate and has an ink reservoir defining a portion of an ink flow path for transporting ink from the ink storing device to the ink chamber of the ink chamber plate. The ink reservoir has at least one tapered portion progressively diverging in a direction toward the ink chamber of the ink chamber plate.
