摘要
The present invention provides a surface-treated silica filler for suppressing an increase in viscosity when added to a resin composition used for applications such as a semiconductor sealing material, and the resin composition containing the surface-treated silica filler. The surface-treated silica filler of the present invention is surface-treated with a basic substance having an acid dissociation constant (pKa) of its conjugate acid of 9.4 or more.
