<p><P>PROBLEM TO BE SOLVED: To provide a heat conducting sheet high in adhesion to a heating element and a radiator, and high in thermal conductivity. <P>SOLUTION: A heat conducting sheet of the present invention includes a heat conducting layer 10 and an adhesive layer 20 provided on both sides or one side of a surface of the heat conducting layer 10. The heat conducting layer 10 includes: (A) a non-spherical particle 12 having a volume resistivity of 10<SP POS="POST">9</SP>Ωm or more and a thermal conductivity of 20 W/mK or more; and (B) an organic polymer compound 14 having a volume resistivity of 10<SP POS="POST">9</SP>Ωm or more and a glass transition temperature (Tg) of 50°C or less. The long axis direction of the non-spherical particle 12 is oriented to follow the thickness direction of the heat conducting layer 10. The adhesive layer 20 contains the organic polymer compound 14 included in the heat conducting layer 10 as a main component. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
