PROBLEM TO BE SOLVED: To manufacture a needle-like body inexpensively by imparting a needle-like body duplication plate with durability.SOLUTION: A needle-like body original plate 101 is filled with a duplication plate material 300 in which additives such as a silica filler 302 are added to a silicone resin monomer 301. By peeling the duplication plate material 300 that has been solidified from a surface of the needle-like body original plate 101, a needle-like body duplication plate 201 made from the duplication plate material 300, is manufactured, in which recessed parts correspond to needle-like parts 503 are formed on a surface. A needle-like body material 510 is disposed on a surface having recessed parts 202, of the needle-like body duplication plate 201. The needle-like body material 510 is pressurized against the needle-like body duplication plate 201, and the needle-like body material 510 is heated and melted to be filled into the surface having the recessed parts 202 of the needle-like body duplication plate 201. In a state that the needle-like body material 510 is filled on the needle-like body duplication plate 201, cooling is performed. The needle-like body material 510 is completely peeled from the needle-like body duplication plate 201, to provide a needle-like body 501.
