An all-purpose wig has a base including an ultrathin and moisture permeable film-shaped material, and hair materials adhered to one surface of the base. A first adhesion layer includes an adhesion agent having comparatively strong adhesion and a comparatively large degree of gelling. A second adhesion layer includes an adhesion agent having comparatively weak adhesion and a comparatively small degree of gelling. The first adhesion layer and the second adhesion layer are provided adjacent to each other with a tank layer therebetween. A first release layer is attached peelably to the whole surface of the second adhesion layer on the side that is fit to the skin, and a second release layer is applied peelably to the first adhesion layer and is layered on a portion of the surface between the first adhesion layer and the tank layer. The layers are layered in order, forming a flat surface.
