Abstract
A cooling device includes: a heat sink including a plurality of fins formed to be plate shaped, which are arranged in parallel to one another; and a cooling fan arranged in a direction from the heat sink, the direction being perpendicular to perpendicular lines of the fins. A plurality of fins of a side heat sink constituting the heat sink include edges aligned on an oblique line with respect to perpendicular lines of the fins and formed on the outer periphery of the cooling fan. With this structure, it is possible to improve usage efficiency of an air flow generated by the cooling fan.
