PROBLEM TO BE SOLVED: To provide a metal porous electrode base material which has a pore structure capable of sufficiently being filled with an electrode material and active material, and also hardly dropping out them therefrom, and can make a battery high in performance. SOLUTION: In the planar metal porous electrode base material 10, a plurality of polyhedrons whose sides are composed of skeletons 11 of a metal sintered compact are formed in a mutually continuous. In the skeletons 11, the thickness of the skeletons 11A arranged at the outermost surface 10A is≥5 to≤65μm, the thickness of the skeletons 11B arranged at the inside is≥3 to≤35μm, also, the thickness of the skeletons 11A in the outermost surface 10A is≥1.2 to≤2.5 times that of the skeletons 11B at the inside, and the voidage of voids 12 formed between the skeletons 11 i≥s 97 to≤99%.
