Abstract: The present invention relates to a heat sink comprising a heat pipe. A heat sink, according to one embodiment of the present invention, comprises: a first heat pipe mounted in a first groove formed on a first surface of a heat sink; a second heat pipe mounted in a second groove formed on a second surface of the heat sink; and a third groove in which at least a portion of the second heat pipe mounted in the second groove is exposed in the direction of the first surface. A method for producing a heat sink comprises the steps of: forming, on a first surface of a heat sink, a first groove in which a first heat pipe is mounted; mounting the first heat pipe on the first surface by disposing and press-fitting the first heat pipe in the first groove; forming, on a second surface of the heat sink, a second groove in which a second heat pipe is mounted; mounting the second heat pipe on the second surface by disposing and press-fitting the second heat pipe in the second groove; and forming a third groove such that at least a portion of the second heat pipe is exposed in the direction of the first surface.
