To provide a method of inexpensively and easily manufacturing a suturing needle with a suture.

A prepared hole 8 is formed along the longitudinal direction of a barrel part 3 from its basic end part 4 toward a tip part side by executing the laser beam machining to the basic end part 4 of the barrel part 3 having a keen needle point part 2 on its tip part. The reaming is executed to the prepared hole 8 to form an inner face shape, whereby a fitting hole part 5 for caulking the suture 6 is formed. The reaming is executed with a taper reamer 11 or a parallel reamer 21.
