PROBLEM TO BE SOLVED: To provide a magnesium oxide filler for compounding in resins, which gives molded articles excellent in moldability, heat conductivity and water resistance, and to provide a heat-conductive resin composition containing the same. SOLUTION: This magnesium oxide filler for compounding in resins, having a purity of≥95.0 mass%, is characterized by having a BET specific surface area of≤5.0 m<SP>2</SP>/g, a volume-average particle diameter (Dv) of 0.5 to 60μm, and a volume-average particle diameter (Dv)/number-average particle diameter (Dn) ratio of 10 to 55.
