Abstract
Provided is a heat conductive foam sheet for electronic equipment sufficiently thin and flexible to be suitably used in the interior of electronic equipment and excellent in heat conductivity. A heat conductive foam sheet for electronic equipment containing a heat conductor in an elastomer resin portion constituting the foam sheet, in which the content of the heat conductor relative to 100 parts by mass of the elastomer resin is 100 to 500 parts by mass, the 25% compressive strength of the foam sheet is 200 kPa or less and the thickness thereof is 0.05 to 1 mm.
