PURPOSE: An ink jet print head is provided to obtain an effect to maintain the proper viscosity of ink by cooling the ink with a thermoelectric element generating a cooling effect when applying power when the temperature of the ink exceeds proper temperature. CONSTITUTION: An ink jet print head(100) comprises an ink damper(110), a temperature sensing unit(120), and a cooling unit(130). Ink is accommodated in the ink damper. The temperature sensing unit senses the temperature of the ink. The cooling unit emits the heat of the ink through a thermoelectric element(131) according to the sensed temperature. The temperature sensing unit is connected to the ink damper and comprises a sensing line(121) transmitting the heat of the ink.
