PROBLEM TO BE SOLVED: To provide a manufacturing method of needle-like objects, the method that enhances release properties of the needle-like objects to the stampers, and even if manufacturing a lot of needle-like objects, a stamper shape is not deteriorated, and thereby the yield of products is high.SOLUTION: An original plate 1 of needle-like objects is made, and the original plate 1 is molded by resin materials, and thereby a father having recesses of the shape corresponding to the original plate is made. Also, the father 2 is molded by the resin materials, and a mother 3 of the shape corresponding to the recesses is made. Then, several mothers 3 are fixed on a surface 4a, and a multifaceted board 5 is made. A metal layer 6 is made on the surface of the multifaceted board 5, and the metal layer 6 is peeled off from the multifaceted board 5 to make a stamper. Further, the needle-like objects are made by using the stampers.COPYRIGHT: (C)2016,JPO&INPIT【課題】スタンパーに対する針状体の離型性を高め、針状体を多く製造してもスタンパー形状が劣化せず、製品の歩留まりの高い針状体の製造方法を提供する。【解決手段】針状体の原版1を作製し、原版1を樹脂材料によって型取りし、原版に対応した形状の凹部を有するファーザーを作製する。また、ファーザー2を樹脂材料によって型取りし、凹部に対応する形状のマザー3を作製する。そして、マザー3を面4a上に複数固定して多面付け版5を作製する。多面付け版5の表面に金属層6を作製し、金属層6を多面付け版5から剥離してスタンパーを作製する。さらに、スタンパーを使って針状体を製造する。【選択図】図1-1
