Abstract
According to an embodiment, an electrospinning apparatus includes: a transport roll; and a head unit. The transport roll is a roll that transports a substrate. The transport has a transport surface that is in contact with the substrate when transporting the substrate. The transport surface of the transport roll has a surface roughness Ra of 1.6 or less. The head unit ejects a raw material liquid of fiber toward the substrate transported by the transport roll to form a film of the fiber on the substrate.
