More Information
Summary:A thermal conductive sheet including cured product of resin composition containing carbon fiber, inorganic filler other than the carbon fiber, and binder resin, the sheet satisfying:(1) tack force of sheet surface is 100gf or greater, determined when the sheet between release films is subjected to press processing at 0.5MPa for 30sec, and immediately after the films are peeled off, is indented by 50µm at 2mm/second with probe 5.1mm in diameter and the probe is pulled away at 10mm/sec; and(2) (B/A)× 100≥80% is true, A denoting tack force(gf) of the sheet surface immediately after the films are peeled off subsequent to the press processing of (1) and B denoting tack force(gf) of the sheet surface when the sheet is indented by 50pm at 2mm/second with probe 5.1mm in diameter and the probe is pulled away at 10mm/second after exposure to atmosphere for 1 hour subsequent to the press processing.
