PURPOSE: To provide an ink jet recording head, its manufacturing method and an ink jet recorder whereby the printing performance and the manufacturing efficiency are improved. CONSTITUTION: In the ink jet recording head, a head chip 12 where nozzles for discharging ink drops are formed is fixed via rubber sealing members 62 and 100 to an opening part 96 of an ink manifold 30. Moreover, the head chip 12 is exposed to the inside of an ink supply chamber 102. Therefore, the head chip 12 is efficiently cooled by ink and an ink temperature can be controlled to within a predetermined range. Since a heat sink is eliminated, manufacturing the ink jet recording head is facilitated and the ink jet recording head is made compact. Since the head chip 12 is fixed via the rubber sealing members 62 and 100, a time for applying and curing an adhesive is eliminated, and the manufacturing efficiency is improved.
