Abstract
A polymer nanofiber structural body of the present invention is a polymer nanofiber structural body in which polymer nanofibers are integrated, including a first layer and a second layer different from each other in polymer nanofiber existence ratio, in which: both the first layer and the second layer are laminated through a buffer region; the buffer region includes a region in direct contact with both the first layer and the second layer; and a polymer nanofiber existence ratio of the region continuously changes from a polymer nanofiber existence ratio of the first layer to a polymer nanofiber existence ratio of the second layer in a direction from the first layer to the second layer.
