In an embodiment, an electrospinning apparatus includes a transfer unit, a spinning head and an air ejection unit. In the transfer unit, a transfer target is transferred along a transfer direction, and a spinning head is capable of ejecting a material liquid toward the transfer unit from a first direction, which intersects the transfer direction. The air ejection unit forms an air flow that flows across the transfer unit toward an area located on an opposite side across the transfer unit in a second direction, which intersects both the transfer direction and the first direction, by ejecting air against the transfer unit from one side of the second direction.
