Abstract: An inorganic filler-containing epoxy resin cured product contains a magnesium oxide powder and has a maximum thermogravimetric mass loss rate ΔRmax of −0.20 mass percent/° C. or more within a temperature range of 300° C. to 500° C. The filling factor of the magnesium oxide powder in the inorganic filler-containing epoxy resin cured product is 45% to 63% by volume.

Abstract: A resin composition including a main agent containing an epoxy compound, a curing agent, and inorganic particles, the curing agent includes an aromatic compound in which a ratio of the number of carbon atoms constituting an aromatic ring to a total number of carbon atoms in one molecule is 85% or more, a content of the inorganic particles is 40 to 75 vol % based on a total amount of components other than a solvent, the inorganic particles include boron nitride particles and particles different from the boron nitride particles, and a content of the boron nitride particles is 3 to 35 vol % based on a total amount of components other than a solvent.
