1. composite capacitor comprises:

  • Substrate, this substrate has a plurality of through holes;

    At least one parallel plate capacitor is positioned on this substrate;

    AndAt least one through hole electric capacity is arranged at least one through hole and in parallel with this parallel plate capacitor, and this through hole electric capacity comprises at least;

    Anodal layer is positioned at the inner surface of this through hole at least, should positive pole layer to the inner surface that is less than through hole be a loose structure wherein;

    First dielectric layer is positioned on this loose structure of this positive pole layer at least;

    First negative electrode layer is covered in the surface of this first dielectric layer;

    AndSecond negative electrode layer is covered in the surface of this first negative electrode layer, and wherein the conductivity of this second negative electrode layer is greater than the conductivity of this first negative electrode layer.
