PROBLEM TO BE SOLVED: To provide a heat conductive sheet having both flame retardancy and heat conductivity. In a sheet obtained by curing a functional group-containing acrylic copolymer exhibiting fluidity at 1013 hPa and 25 ° C. with a crosslinking agent, the crosslinking density is 80% or more in the gel fraction of THF extraction, And it is set as the flame retardant heat conductive sheet containing expanded graphite as a filler. In addition, by adding an inorganic compound having crystal water such as aluminum hydroxide and magnesium hydroxide together with expanded graphite as a filler, the flame retardant heat conductive sheet is further improved in both flame retardancy and thermal conductivity. Is obtained. [Selection figure] None |
