A printer head is provided that enhances energy efficiency of a heater layer and substantially prevents heat from being excessively transmitted to ink in an ink chamber, thereby improving ink-ejecting performance and/or printing performance. A method of fabricating such a printer head is also provided. The print head includes a substrate having an ink chamber and a nozzle disposed in the top thereof, an insulating layer layered on the substrate, and a heater layer layered on the insulating layer. A heat transmitting part transmits heat to the ink chamber. The insulating layer is formed so that a portion thereof that faces the heat transmitting part of the heater layer has a thickness larger than that of the rest of the insulating layer.
