PROBLEM TO BE SOLVED: To provide a manufacturing method of a clip for a blood vessel made of a synthetic resin capable of obtaining uniform clipping force when being used； and to provide a clip for a blood vessel made of a synthetic resin.SOLUTION: In a manufacturing method of a clip for a blood vessel made of a synthetic resin, an assembly component having a knob part and a long piece part extending from the knob part is molded integrally of a synthetic resin material, and after molding, assembly is carried out against resin elasticity so that a projection piece on the rear of the knob part abuts mutually on the rear of the other knob part, to thereby become rotatable on the shank, and therefor the long piece part can occlude by resin elasticity by deformation of the projection piece.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】使用に際して均一なクリップ力を得ることができる合成樹脂製血管用クリップの製造方法及び合成樹脂製血管用クリップを提供する。【解決手段】合成樹脂製血管用クリップの製造方法は、摘み部と該摘み部から延びる長片部とを有する組立構成品を合成樹脂材で一対成形し、成形後に前記摘み部の裏側の突出片が互いに他方の摘み部の裏側に当接するように樹脂弾性に抗して組立して軸部で回動可能に連結し、前記突出片の変形による樹脂弾性で前記長片部が咬合可能となる。【選択図】図４
