A heat conductive sheet excellent in heat dissipation and heat resistance of a cured product is provided. A heat conductive sheet according to the present invention includes a fibrous base material, a resin composition impregnated in the fibrous base material, or a reaction of the resin composition impregnated in the fibrous base material. And a reaction composition obtained by proceeding. The resin composition has a weight average molecular weight of 1000 or less, a radical polymerizable compound (A) having a carbon-carbon double bond, a photoradical generator (B), and a weight average molecular weight of 600 or less. , A curable compound (C) having no carbon-carbon double bond and having an epoxy group or an oxetane group, a thermosetting agent (D), and a filler having a thermal conductivity of 10 W / m ยท K or more (E ). In the total 100% by weight of all resin components in the resin composition, the content of the radical polymerizable compound (A) is 20 to 60% by weight, and the content of the curable compound (C) is 10 to 60% by weight. %.
