PROBLEM TO BE SOLVED: To provide a heat sink, which can dissipate heat very efficiently and is easily formed as well as being miniaturized. SOLUTION: This heat sink is provided with a heat conductor 12 mounted with electronic elements 10, which are accompanied by a heat generation, piezoelectric vibrators 16 to curve the heat conductor 12 provided in a prescribed range on the surface, where is not mounted with the element 10, of this conductor 12 and a driving means to make the vibrators 16 take expansion and contraction actions. The conductor 12 is tabularly formed and the vibrators 16 are laminated on both surfaces in the prescribed range of the conductor 12.
