A disposable wig, comprising a base (1) formed of an extremely thin sheet, implanted hair materials (3) implanted in the base, and an adhesive layer (7) installed on the rear surface of the base. Thethickness of the base is in unit of micron (mu). The adhesive layer is formed on the entire rear surface of the base with such a uniform thickness that irregularities are formed between the projectedparts (9) put over the root parts (5) of the implanted hair materials projected from the rear surface of the base and the other portions, and when the wig is fitted to the skin of a person, the projected parts are raised to the surface side of the base. When the wig is fitted onto a scalp (13), the irregularities on the rear surface of the base are pressed by the surface of the scalp and raised, and the projected parts put over the root parts on the surface of the base are brought in a state that are raised from the other portions. Accordingly, light hitting the base is irregularly reflected,and the wig becomes hard to be distinguished from true hair. Since the implanted hair materials are brought in a state of being pressed by the scalp on the surface side of the base, the fixing of theimplanted hair materials is reinforced and the implanted hair materials are prevented from being released (so-called the epilation).
