A writing instrument containing nanosilver is provided to protect bacterial infection on its surface, have antibiosis and protection against poison, and is capable of generating anion. The writing instrument(10) has its holding part that consists of synthetic resin, plastic resin, metal, wood, rubber, or silicone. The writing instrument(10) containing nanosilver is obtained by a process(100) of mixing a nanosilver solution or nanosilver powder(20) with raw materials to be molded during its production, or a process(110) of applying nanosilver(20) to the surface of the writing instrument(10). The nanosilver is added in an amount of 0.01wt%-50wt% or 2ppm-999ppm, or is applied to the surface of the writing instrument in a thickness of 0.001mm-20mm. |
