    • A solid capacitor having an embedded electrode includes a substrate unit, a first conductive unit, a second conductive unit, a first insulative unit, a third conductive unit, a second insulative unit, and an end electrode unit. The substrate unit includes a substrate body and a conductive body embedded into the substrate body. The substrate body has a lateral opening and a plurality of top openings, and the conductive body has a lateral conductive area exposed from the lateral opening and a plurality of top conductive areas respectively exposed from the top openings. The first conductive unit includes a plurality of first conductive layers respectively covering the top conductive areas. The second conductive unit includes a second conductive layer covering the first conductive layers. The porosity rate of the second conductive layer is larger than that of each first conductive layer.
