<p>Disclosed are: a novel hydrotalcite compound, which is capable of serving as an anion scavenger that traps harmful anions in a resin composition or the like, and which does not deteriorate the (melt) fluidity of a resin composition; and a resin composition for electronic component encapsulation.Specifically disclosed is a spherical hydrotalcite compound which is represented by formula (1) below and has a peak of a hydrotalcite compound in a powder X-ray diffraction pattern, a specific surface area as determined by a BET method of 30-200 m2/g (inclusive) and a volume-based median diameter of secondary particles as measured by a laser diffraction particle size distribution measuring instrument of 0.5-6μm (inclusive).(MgxZn1-x)aAlb(OH)c(CO3)d·nH2O (1)In formula (1), a, b, c and d respectively represent a positive number and satisfy 2a + 3d - c - 2d = 0; x satisfies 0.5≤x≤1; and n represents the number of hydration, which is 0 or a positive number.</p> |
