Provided are a bending method and a bending apparatus for bending a medical suturing needle into different curved shapes by using one bending top. The bending apparatus comprises a reciprocally rotatable bending top, and a belt having such a flexibility as can be wound on the outer circumference of the bending top. The bending method curves a medical suturing needle by sandwiching and constricting a material for the medical suturing needle between the bending top and the belt and by rotating the bending top reciprocally in the winding direction and in the rewinding direction. In the bending method, the curved shape of the material is changed by changing the winding angle of the belt to be wound on the outer circumference of the bending top thereby to change the area for constricting the material. The bending apparatus (B) comprises a reciprocally rotatable bending top (11), and a belt (12) having such a flexibility as can be wound on the outer circumference of the bending top (11), and is constituted such that a winding angle (θ) for the belt (12) to be wound on the outer circumference of the bending top (11) is changed.
