Abstract To provide an electrospinning head which suppresses complication of a constitution and a control system, increase in manufacturing cost, and decrease in productivity, and appropriately forms a film of a fiber having a large dimension in the width direction.SOLUTION: An electrospinning head 2 comprises a plurality of head units 21A, 21B and a connecting structure, and the plurality of head units 21A, 21B are connected to each other by the connecting structure. Each of the plurality of head units 21A, 21B includes a unit body 23 and a nozzle 12. A cavity 25 for storing a raw material liquid is formed in the unit body 23 along the longitudinal axis. The nozzle 12 is formed of a conductive material and provided on the outer peripheral surface of the unit body 23. The nozzle 12 jets the raw material liquid supplied through the cavity 25 of the unit body 23. The connection structure connects the plurality of head units 21A, 21B in a state where cavities of the unit body communicate with each other.SELECTED DRAWING: Figure 1 【課題】構成及び制御系の複雑化、製造コストの増加、及び、生産性の低下が抑制されるとともに、幅方向の寸法が大きいファイバーの膜を適切に形成する電界紡糸ヘッドの提供。【解決手段】電界紡糸ヘッド2は、複数のヘッドユニット21A、21B及び連結構造を備え、複数のヘッドユニット21A、21Bは、連結構造によって、互いに対して連結される。複数のヘッドユニット21A、21Bのそれぞれは、ユニット本体23及びノズル12を備える。ユニット本体23の内部には、原料液を収納する空洞25が長手軸に沿って形成される。ノズル12は、導電材料から形成されるとともに、ユニット本体23の外周面に設けられる。ノズル12は、ユニット本体23の空洞25を通して供給される原料液を、噴出する。連結構造は、ユニット本体の空洞が互いに対して連通する状態で、複数のヘッドユニット21A、21Bを連結する。【選択図】図1
