Abstract
A polymer nanofiber sheet including polymer nanofibers having a polymer, the polymer nanofibers being accumulated and three dimensionally entangled. The polymer nanofiber sheet has a low molecular weight organic compound containing at least one 4- or higher-membered ring structure with an ether linkage. The difference between the average solubility parameter of the polymer and the average solubility parameter of the low molecular weight organic compound is less than 8 (J/cm).
