An ink flow path of improved structure in an ink jet printer head includes a first ink channel formed at a right angle to an ink supply path in parallel relation with an ink chamber, a second ink channel formed at a right angle to the first ink channel in parallel relation with the ink supply path across the ink chamber, and a third ink channel connecting the second ink channel to a rear side of the ink chamber of which front side faces the ink supply path. Accordingly, a backflow of ink is prevented during the ink discharge through a nozzle hole, thus print quality is improved.
