Polishing method, brush-like grinding stone, polishing brush, and linear member aggregate

A brush-like grinding stone comprising:

• linear member aggregates, each of which includes a bundle of linear members and a linear member holder to which an end of the bundle is fixed;
• and
• a brush holder having a plurality of holding holes that are open in one side in an axial line direction, the linear member holders being detachably attached to the respective holding holes,
• wherein the brush holder is provided with a through hole in communication with one of the holding holes at a position overlapping one of the linear member holder on the other side opposite to the one side in the axial line direction when viewed in the axial line direction,
• linear member holders are detachably attached to the respective holding holes in the brush holder with the threaded fixing mechanism,
• one of the linear member holders is provided with a first fixing hole passing therethrough in a direction orthogonal to the axial line direction in a part opposite to a side to which the linear members extend,
• the brush holder is provided with a second fixing hole passing therethrough from the outer circumferential surface of the brush holder to one of the holding holes, and a third fixing hole open on an inner wall of the one of the holding holes opposite to the second fixing hole at a position in communication with the first fixing hole, and
• the threaded fixing mechanism includes a female thread and a set screw, the female thread being formed in an inner circumferential surface of the third fixing hole, and the set screw being configured so as to be set in the female thread through the first fixing hole.
