PROBLEM TO BE SOLVED: To provide a method for manufacturing a hydroxide particle that solves the problems in lowering of the amount of crystallization water when granulated by adding a binder and heated in order to remove the binder, and in forming an ununiform granule due to low density. SOLUTION: The manufacturing method comprises adding and mixing an aluminum hydroxide powder and a hydroxide powder of group II element to obtain the raw material powder containing 26-34 wt.% of the crystallization water comprised of OH group, adding water to the resultant raw powder, mixing and granulating the same to obtain the granule, then regulating the particle size and drying at the temperature so as not to release the crystal water, thereby obtaining the particle of which water content is 0.3 wt.% or less.
