摘要

An ink-jet print head chip, method for manufacturing the ink-jet print head, structure for connecting the ink-jet print head chip and a flexible printed circuit board and method for connecting the ink-jet print head chip and the flexible printed circuit board are provided to reduce the time required for connecting the ink-jet print head chip to the flexible printed circuit board by simultaneously connecting a plurality of lead lines of the flexible printed circuit board to a plurality of connection pads of the ink-jet print head chip. An ink-jet print head chip(100) comprises a nozzle unit including a plurality of nozzles, a plurality of connection pads(107) and an overflow prevention protrusion(110). The connection pads are installed at a side of the nozzle unit and are electrically connected to a plurality of ink discharging parts, which are formed at a lower part of the nozzle unit. The overflow prevention protrusion is installed between the nozzle unit and the connection pad and has a height higher than that of the connection pad.
