An LED(Light-Emitting Diode) printer head is provided to improve a performance stability of the LED printer head by offering a graphite heat sink having higher thermal conductivity than that of metal one. In an LED printer head, a housing(100) has an exposed lens(110) on one side thereof. An LED is installed on an inside of the housing to irradiate light to the lens. A heat sink(200) of graphite material is installed on one side of the housing in an opposite position of irradiating direction of the LED to radiate heat generated from the LED to outside. And, the heat sink is formed by mixing the graphite material and the resin.
