Abstract
With respect to a plate-shaped hydrotalcite in which the average width of primary particles is increased, (1) the aspect ratio of secondary particles is increased by suppressing aggregation of primary particles by relatively reducing the average thickness thereof, and 2) the formation of a by-product that impairs the transparency of a resin is suppressed. Provided is a plate-shaped hydrotalcite represented by a formula (1) below:(M)(M)(OH)(A)HO  (1)
