Abstract
An amorphous silica powder that is suitable for obtaining a liquid sealant that exhibits superior filling properties and preservation properties, and a resin composition obtained by using the amorphous silica powder as a filler. More specifically, an amorphous silica powder is prepared so as to have a modal diameter within the range of 1 to 10 μm and a frequency of particles having particle diameters of less than 0.50 μm of 1.0% or more in the particle diameter frequency distribution and have a specific surface area of 1 to 12 m2/g.
