A production method that includes: a first step for dissolving aluminum hydroxide in an alkaline solution and preparing an aluminate solution; a second step for reacting the aluminate solution obtained in the first step with carbon dioxide and precipitating a low-crystallinity aluminum compound; a third step for mixing the low-crystallinity aluminum compound obtained in the second step with a magnesium compound to perform a first-order reaction and preparing a reactant that includes hydrotalcite core particles; and a fourth step for performing a hydrothermal reaction on the reactant obtained in the third step and synthesizing hydrotalcite particles. The production method makes it possible to obtain hydrotalcite particles that: can impart excellent heat resistance, transparency, fluidity, or the like; and can be used as a resin stabilizer or the like.
