The instant invention provides a capacitor package structure having a functional coating and the method for manufacturing the same. The method includes coating a silane coupling agent with a general formula of Y(CH2)nSiX3 on a capacitor element for forming the functional coating, in which X can be a same or different substituents and is selected from the group consisting of chloride, methoxy group, ethoxy group, methoxyethoxy group and acetoxy group, Y is a vinyl group, an amino group, an epoxy group, a methacryloyloxy group, a thiol group, a uramino group or an isobutyl group; and coating a conductive dispersion on the functional coating for enabling a polymer composite material in the functional coating to be connected to the surface of the capacitor element through the silane coupling agent.
