To provide a method for manufacturing brush bristles used for removing attached objects such as pills attached to clothes such as sweaters, carpets and the like; and to provide a brush manufactured by the same method.

This method for manufacturing pill-removing brush bristles includes: bringing brush bristles 2 filling a base plate 3 into contact with a metal plate 1 for thermal process, with the bristle tips coming into press contact therewith, wherein the metal plate 1 is formed by cutting lattice-shaped grooves M on a flat surface such that flat plate parts M1 and recessed parts M2 are formed alternately adjoined with each other; and forming nailhead-shaped deformed portions 2a having two types of different heights (high and low) at the tips of the respective brush bristles 2 based on thermal denaturation.
