To easily adjust a protrusion dimension of a needle protruding from a tip of an injection needle formation body and an orientation of a cutting plane.SOLUTION: An injection needle formation body comprises a formation body main body and a hollow needle 12. A tip of the needle comprises a cutting plane cut in an oblique direction to a longitudinal direction of the needle. A jig 1 comprises: a device main body; and one or more insertion holes formed from a top surface of the device main body to a lower side. The insertion hole is set to have a depth equal to or greater than a length of the needle protruding from a contact surface. A lower side of the insertion hole has a contact part to which at least a part of the cutting plane contacts. In a state in which at least a part of the cutting plane contacts the contact part, the needle is inserted into the formation body main body.SELECTED DRAWING: Figure 11 【課題】注射針形成体の先端から突出する針の突出寸法及び切断面の向きを、簡易に調整すること。【解決手段】注射針形成体は、形成体本体と、中空の針１２と、を有する。針の先端部には、針の長さ方向に対して斜めに切断された切断面が形成される。治具１は、装置本体と、装置本体の上面から下方に向かって形成される１つ以上の挿入穴と、を有する。挿入穴は、当接面から突出する針の長さ以上の深さに設定される。挿入穴の下方には、切断面の少なくとも一部を当接させる当接部が形成される。切断面の少なくとも一部が当接部に当接した状態で、針が形成体本体に挿通される。【選択図】図１１
