A electrode frame having the first frame group covered the first conductive frame strip, and the first conductive frame strip has first frame strip conductive component and multiple first substrate conductive components; the second frame group covered the second conductive frame strip, and the second conductive frame strip has second frame strip conductive component and multiple second substrate conductive components; when the first frame group and the second frame group are combined, above mentioned components are all electrically connected; the conductive hanger conducts electricity to the inner frame strips, then conducts electricity to the first and second substrate conductive components, and the substrate conductive components separately electrically connect to lateral side of the substrate for making the electric current conduct uniformly on the both lateral side and the surrounding of the substrate.
