To provide an assistant tool enabling the touch reading of braille at high touch reading speed with a low misreading rate.

The microfiber assembly for assisting the touch reading of the braille, including fibers having an average fiber diameter of 0.01-10 m and stuck at least at parts of neighboring fibers has a thickness of 10-50 m, an average compactness of 30-95%, and a dynamic friction coefficient on the surface of 0.25 m, and preferably further has a tensile strength of 45-200 MPa. The assistant tool of the touch reading of the braille is made of the microfiber assembly.
