Abstract
A resin composition for use in a dielectric layer of a capacitor device or a capacitor-embedded printed circuit board is provided in which the resin composition can improve stability in capacitance and insulation properties of the capacitor device under high temperature and high humidity and ensures high adhesion of the dielectric layer to the device. The resin composition comprises a resin component and a dielectric filler. The resin component comprises an epoxy resin, an active ester resin, and an aromatic polyamide resin.
