ELECTROSPINNING APPARATUS

To provide a technique enabling mass production of ultrafine fibers.SOLUTION: A spinning head 4 has a first divided body 42 and a second divided body 43, and a liquid flow path used for moving a raw material liquid is formed on a stacked face formed by stacking both divided bodies 42, 43. The spinning head 4 has a plurality of protrusions 41 intermittently arranged in a first direction X and protruding in a second direction Y. A discharge port 48, which is a downstream end in the moving direction of the raw material liquid in the liquid flow path, is located at the tip of the protrusion 41. The tip of the protrusion 41 has the shortest length in a third direction Z in the spinning head 4.SELECTED DRAWING: Figure 2 【課題】極細繊維の量産化を可能にする技術を提供すること。【解決手段】紡糸ヘッド４は、第１分割体４２と第２分割体４３とを有し、両分割体４２，４３を重ね合わせた重合面に、原料液の移動に使用される液体流路が形成されている。紡糸ヘッド４は、第１方向Ｘに間欠配置され、第２方向Ｙに突出する複数の突出部４１を有する。突出部４１の先端に、前記液体流路における原料液の移動方向の下流側端である吐出口４８が位置している。突出部４１の先端は、紡糸ヘッド４において第３方向Ｚの長さが最も短い。【選択図】図２
