摘要: Provided is a heat dissipation sheet capable of effectively enhancing adhesiveness and long-term insulation reliability. The heat dissipation sheet according to the present invention contains first inorganic particles having an aspect ratio of 2 or less, second inorganic particles having an aspect ratio of more than 2, and a binder resin. In this heat dissipation sheet, a content of the second inorganic particles is larger than a content of the first inorganic particles in 100% by volume of a region having a thickness of 15% on a first surface side in a thickness direction, and the content of the first inorganic particles in 100% by volume of the region having a thickness of 15% is larger than the content of the first inorganic particles in 100% by volume of a central region having a thickness of 70%.
