The present invention provides a porous electrode used for a conductive material-filled polymer composite. At least one surface of the porous electrode is an open porous structure, which includes a plurality of macropores and micropores randomly distributed and interconnected with each other. The conductive material-filled polymer composite includes a polymer substrate and conductive particles filled therein. When the surface of the open porous structure of the porous electrode is bonded with the conductive material-filled polymer composite, the conductive particles in the conductive material-filled polymer composite can be trapped in the macropores of the porous structure, and the polymer substrate in the conductive material-filled polymer composite can be immersed into the micropores of the porous structure. This enables a better direct contact between the conductive particles and the porous electrode. There is good adhesion strength between the porous electrode and the conductive material-filled polymer composite, and the interfacial resistance is decreased.
