A monofilament fabricated by a process in which a melt spinning and drawing treatment are carried out after particles of silver ceramics are mixed with a resin material for a fiber having a principal component of polybutylene terephthalate. The particles of the silver ceramics have a size of 5.0 mu m or less, and the content of the particles of the silver ceramics in the mixture is within a range of 0.3% to 3.0%. Then, the surface of the monofilament is subjected to a mechanical delustering treatment, thus obtaining artificial hair having low bacterial infection rate, high fixation rate of implanted hairs, and high durability, such that the hair does not break at a point near the root part even after having been used for a long period of time after implantation. |
