The invention relates to a vertically-partitioned metallized grid safe film electrode structure, which comprises an upper layer metallized safe film and a lower layer metallized safe film. One side of each layer of the metallized safe films is a clad layer-free residual side, and the other side of each layer of the metallized safe films is a clad layer-thickened side; continuous clad layer zones and grid pattern zones which have roughly equal width are vertically distributed on a clad layer between the residual side and thickened side at intervals and alternately; small electrodes in the gridpattern zones do not interconnect directly; when two layers of the metallized safe films are overlaid for wrapping a capacitor, the residual sides and the clad layer-thickened sides of the upper and lower layers correspond to each other alternately; and the continuous clad layer zones and the grid pattern zones of the upper and lower layers correspond to each other alternately at the same time. The vertically-partitioned metallized grid safe film electrode structure has small overall heat productivity, is suitable for manufacturing alternating-current capacitors and high-frequency capacitors,increases safe reliability and service life, reduces the loss rate of the effective area of the film due to the gap stripes of an pattern, and reduces the manufacturing cost of a safe film capacitor.
