Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gibbsite type aluminum hydroxide particle exhibiting higher fire resistance. SOLUTION: The gibbsite type aluminum hydroxide particle is characterized in that it has a primary particle size of 0.01-0.3 μm and a DOP oil absorption of 90-300 mL/g. The BET specific surface area is preferably 10-100 m2/g. The gibbsite aluminum hydroxide particle is manufactured by preparing an aluminum hydroxide slurry by precipitating aluminum hydroxide by partially neutralizing a sodium aluminate aqueous solution, and aging the aluminum hydroxide slurry at a temperature of 40 to 90°C.
