A heat sink for dissipating a heat from an object includes a plurality of fins. The fins are arranged radially about a center axis to be spaced away from one another, and extend outward in a radial direction substantially perpendicular to the center axis. Each fin is branched at at least two different positions in the radial direction into at least three fin end portions spaced away from one another.
