Abstract
According to an embodiment, an electrospinning head includes a nozzle and an uneven surface. The nozzle is made from an electrically conductive material, and a flow path is formed inside the nozzle. On the outer surface of the nozzle, an ejection port capable of ejecting a material liquid supplied to the flow path is formed. The uneven surface is formed in the vicinity of the projection port on the outer surface of the nozzle, and an uneven shape of the uneven surface is formed around the entire circumference of the circumferential direction of the nozzle and is along the extending direction of the flow path.
Claims6
An electrospinning head comprising:
- a nozzle made from an electrically conductive material, a flow path being formed inside of the nozzle and an ejection port being formed on an outer surface of the nozzle, the ejection port being capable of ejecting a material liquid supplied to the flow path;
- and
- an uneven surface formed in a vicinity of the ejection port on the outer surface of the nozzle, the uneven surface being formed in an uneven shape around an entire circumference in a circumferential direction of the nozzle, the uneven surface being along an extending direction of the flow path, each of projections being formed in a ring shape and the projections and depressions being alternatively arranged in the uneven surface.
