PROBLEM TO BE SOLVED: To provide a heat-conductive sheet having high heat conductivity and fire retardancy, and improve shape followingness to an element generating heat by combining a base fabric formed of a polybenzazole fiber, which is excellent in heat resistance, strength, fire retardancy and heat conductivity, and a silicone rubber layer containing a heat-conductive filler. SOLUTION: A heat-conductive sheet is composed of a silicone rubber layer containing a heat-conductive filler and a base fabric formed of a polybenzazole fiber, and is obtained by combining the silicone rubber layer containing the heat-conductive filler and the base fabric formed of the polybenzazole fiber. To combine, the base fabric formed of the polybenzazole fiber is laminated on at least one side of the silicone rubber layer containing the heat-conductive filler, or the base fabric formed of the polybenzazole fiber is arranged inside the silicone rubber layer containing the heat-conductive filler. For example, a filament woven fabric 2 formed of the polybenzazole fiber is laminated on one side of a silicone rubber layer 1 containing an aluminum oxide as the heat- conductive filler.
