Abstract
A ring-shaped packing is fitted into a annular groove surrounding an aperture through which ink is supplied to a head unit, and a sealant is filled around the packing. By bringing the packing into contact with the surface of a filter covering a supply hole and by pressing the head unit, the sealant makes intimate contact with the head unit while the end of the packing is kept in intimate contact with the filter, thereby sealing the supply hole. Then a frame and the head unit are bonded to each other using an UV adhesive.
