A head lamp for vehicle using an LED is provided to reduce a manufacturing cost thereof by integrating a plurality of small-sized LEDs instead of bigger LEDs. A low beam irradiation unit(100) includes a plurality of LED lamps. The low beam irradiation unit is positioned at an outside of a head lamp(10). A wide beam irradiation unit(200) is connected to the plurality of LED lamps and is positioned at an intermediate part of the head lamp in order to be operated according to an operation of the low beam irradiation unit. A high beam irradiation unit(300) is connected to the plurality of LED lamps and is positioned in the inside of the head lamp. The low beam irradiation unit includes a base plate, a first heat-radiating pin formed on a rear surface of the base plate, and a first heat-radiating pin installed in a front surface of the base plate. The first heat-radiating pin is connected to the LED lamp in order to radiate the heat of the LED lamp.
