PROBLEM TO BE SOLVED: To easily adjust a protrusion dimension of a needle projected from a tip of an injection needle formation body and an orientation of a first cut surface of a tip of the needle.SOLUTION: An injection needle formation body 70 has a hollow needle 12, a tip of a needle has a first cut surface which is cut obliquely to a longitudinal direction of the needle, and a base end part of the needle has a second cut surface which is cut obliquely to a longitudinal direction of the needle. A jig 1 comprises: a jig body 2； and one or more insertion holes 21 formed from a top surface 25 of the jig body to a lower side. The jig body is provided inside of a base 10. A lower part of the insertion hole has a storage part for storing the base end part of the needle. A lateral width of the storage part is smaller than a diameter of the needle. The storage part contacts at least a part of the second cut surface of the needle inserted into the insertion hole. The injection needle formation body further has a correction part for correcting an orientation of the second cut surface and a depth of insertion of the needle.SELECTED DRAWING: Figure 11COPYRIGHT: (C)2020,JPO&INPIT【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針の先端の第１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７０は中空の針１２を有し、針の先端部は針の長さ方向に対して斜めに切断された第１切断面が形成され、針の基端部は針の長さ方向に対して斜めに切断された第２切断面が形成される。治具１は、治具本体２と、治具本体の上面２５から下方に向かって形成される１つ以上の挿入穴２１と、を有し、治具本体が、基台１０の内側に設置される。挿入穴の下部には、針の基端部を収容する収容部が形成される。収容部の横幅は、針の直径よりも小さく形成される。収容部には、挿入穴に挿入される針の第２切断面の少なくとも一部に当接する。第２切断面の向きと針の挿入の深さとを矯正する矯正部が形成される。【選択図】図１１
