Abstract

A heat sink includes a plurality of heat-radiating fins provided on a base, wherein the heat-radiating fins each have a projection-and-recess shape in which a sectional shape along the base is inscribed in a regular hexagon, wherein projections of the projection-and-recess shape are held in contact with the regular hexagon. In adjacent heat-radiating fins, sides of the regular hexagon, with which the projections are held in contact, are opposed to each other in an entire region. The heat-radiating fins are arranged so that distances between the sides opposed to each other at a distance are equal.
