A heat conducting sheet including a composition, wherein the composition contains plate-form boron nitride particles (A) having an average particle diameter of more than 10 μm and 60 μm or less, and an organic polymer compound (B) having a glass transition temperature (Tg) of 50° C. or lower, the plate-form boron nitride particles (A) are contained in the composition in an amount ranging from 45 to 75% by volume thereof, and are oriented to direct the major axis direction thereof along the thickness direction of the sheet. Thus, there is provided an electrically insulating and heat conducting sheet which can keep a high thermal conductivity while the sheet has additional properties such as flexibility. |
