Abstract

A polymer porous film includes a first layer and a second layer. The first layer is porous. The first layer has a three-dimensional network structure. The second layer is non-porous in an image at a magnification of 50,000x. A proportion of the second layer is more than 0% and less than 10%. The proportion of the second layer is calculated by the following expression: "proportion (%) of the second layer = (t₂/t₀) × 100". t₀ represents a thickness of the polymer porous film. t₂ represents a thickness of the second layer.
