<p>A seal rubber for use in print heads, ink jet printing apparatuses, or the like that enables print heads or the like to be appropriately manufactured while preventing the seal rubbers from sticking mutually, is provided. More specifically, a seal rubber (H1800) provided in a joint section between a print head and an ink tank has a roughened surface for an appropriate surface roughness. Thus, even when a parts feeder is used to supply a large number of mixed seal rubbers during manufacture of print heads, the seal rubbers can be prevented from sticking mutually and can be properly separated for supply. <IMAGE></p> |
