A brush comprising:

• a bristle section, which includes a plurality of fiber bundles and a plurality of binding fibers, which bind and couple the fiber bundles together;
• and
• a base, which has a clamping part for clamping a proximal end of the bristle section, wherein
• the fiber bundles are arranged in a row in a direction perpendicular to a direction in which fibers of the fiber bundles extend,
• the fiber bundles have bent portions at the proximal end of the bristle section,
• the binding fibers are sequentially adjacent in a direction in which the fibers of the fiber bundles extend,
• the clamping part clamps the proximal end of the bristle section to cover the binding fibers, and
• adjacent ones of the binding fibers are in contact with each other between the clamping part and the fiber bundles.
