The present invention relates to a printing steel plate structure for printing a positive silver electrode of a battery, which comprises a planar membrane mesh and a pattern membrane layer. The planar membrane mesh is provided with evenly distributed permeation holes. A bus blanking area of solar cell positive silver electrodes and a finger-like electrode blanking area of solar cell positive silver electrodes with hollows are defined in the planar membrane mesh, characterized in that the longitudinal section of the permeation holes is a square, round, trapezoidal, regular polygonal or stepped shape with rounded corners. The pattern membrane layer is located under the planar membrane mesh, and the pattern membrane layer has a finger-like electrode blanking area of solar cell positive silver electrode with hollows and a bus electrode blanking area. The finger-like electrode blanking area of the planar membrane mesh is provided with a bridge structure pattern just like that of the planar membrane mesh structure, for connecting a corresponding side edge of each finger-like electrode blanking area. Preferably, the bridge structure pattern is located in the middle section of the finger-like electrode blanking area of the planar membrane mesh.
