1. A radiator for electronic parts, comprising:
- a heat receiving surface for receiving heat from a heating generating element; and
a radiating element for radiating heat transferred from said heat receiving surface;
a first through-hole opened at one end to said heat receiving surface and opened at an opposite end;
wherein, in response to a heat conductive semifluid material being positioned between the heat generating element and said heat receiving surface, said heat conductive semifluid material is being driven up and down in said first through-hole in response to changes in temperature.

Abstract
To prevent generation of air bubbles in thermal grease 37 when a wired board 24 is bent due to a difference of thermal expansibility between a CPU chip 31 and a heat sink 32 in a CPU package 21, the thermal grease 37 being filled between the CPU chip 31 and a plate member 34 of the heat sink 32. A through-hole 38 is formed almost in the center of a plate member 34 so as to go through the plate member 34.
