Provided are: magnesium hydroxide particles that have a purity of at least 98 mass%, are hexagonal prism particles of which the outer crystal shape comprises two hexagonal base surfaces at the top and the bottom that are parallel to each other and six outer peripheral prismatic surfaces formed between the base surfaces, and are characterized by the size along the c-axis of the hexagonal prism particles being 0.5-1.5 mum, the size in the c-axis direction being at least 60% of the median particle size of the hexagonal prism particles, the inflection point diameter being 0.1-0.4 mum, and the inter-particle gap being 0.6×10-3-1.0×10-3 m3·kg-1; and a resin composition containing the magnesium hydroxide particles. |
