PROBLEM TO BE SOLVED: To provide a two-piece binder comprising a staple and a supporting member for preventing the buckling of the staple. SOLUTION: Silicone S is applied to an inlet portion of a hole 4a of the supporting member 4 to be fitted to a leg portion 3a of the staple 3. With the silicone applied to the face of the supporting member to be fitted to the staple, a dynamic friction coefficient is greatly reduced to permit the supporting member to be fitted to the staple with lower pressure. Under such conditions that resisting force is greatly changed with a dimensional tolerance or a surface condition, a temperature and a press-in speed during fitting, stable press-in is carried out without the buckling of the staple.
