The present invention relates to a heat sink. It is an object of the present invention to provide a heat sink at a low manufacturing cost, the life of the motor of which is long so that the reliability of the heat sink can be enhanced and, further, a sufficiently high cooling performance can be obtained and the designing of the heat sink can be easily performed. The heat sink includes: a bottom surface coming into contact with a heating element; a side on which a plurality of ventilation holes are formed; and an upper surface into which a cooling fan composed of blades and a motor is embedded and fixed.
