An ink-jet printer line head is provided to prevent printing errors caused by an overheated head tip by efficiently cooling a head tip in the ink-jet printer line head. An ink-jet printer line head comprises a head tip(1), an ink path structure(40), and a plurality of cooling paths(100). The head tip includes a nozzle plate(10), a compressing chamber plate(20), and a silicon chip(30). Nozzles(11) are formed on the nozzle plate in regular intervals. A compressing chamber(21) is formed on the compressing chamber plate for generating pressure to discharge ink. A heater(31) and a driving circuit are formed on the silicon chip. The head tip is fixed on the ink path structure and feeds the ink to the compressing chamber through an ink path(41). The cooling path is formed on the compressing chamber plate between the compressing chambers near the nozzles for efficiently cooling heat generated near the nozzles.
