Disclosed herein is a separator for an electrochemical element， comprising a fibrous structure， wherein the fibrous structure has a first fibrous layer part in which short fibers and/or pulp-like fibers are intertwined with each other， and a second fibrous layer part; some of the short fibers and/or the pulp-like fibers constituting the first fibrous layer part penetrates the second fibrous layer part; and a pore diameter distribution of the fibrous structure satisfies the following formula: 0 μm<D max<18 μm， and 0 μm≤(D max??Dave)<13 μm， wherein D max is a maximum pore diameter (μm) of the fibrous structure， and Dave is an average pore diameter (μm) of the fibrous structure.
