摘要:
PROBLEM TO BE SOLVED: To provide a method of manufacturing an original plate with a plurality of needle-like projections, which enables the original plate to be manufactured in a short period of time, and a method of manufacturing a microneedle array.SOLUTION: A method of manufacturing an original plate with needle-like projections includes: a preparation step of preparing a base material and a cutting tool comprising at least one blade assuming a shape imitating an outer shape of the needle-like projection; and a cutting step of forming the needle-like projection assuming a shape imitating a shape of the cutting tool, by cutting the base material while rotating the cutting tool around the tool axis of the cutting tool and revolving the cutting tool around the axis of the needle-like projection formed on the base material.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】 短い時間で原版を製造することを可能にする、複数の針状突起を有する原版の製造方法、及びマイクロニードルアレイの製造方法を提供する。【解決手段】針状突起を有する原版の製造方法は、針状突起の外形に倣う少なくとも1枚の刃を備える切削工具、及び基材を準備する準備工程と、切削工具を、切削工具の工具軸線を中心に自転させ、かつ切削工具を、基材に形成する針状突起の軸線を中心に公転させ、基材を切削し、切削工具の形状に倣う形状の針状突起を形成する切削工程と、を有する。【選択図】図5
