    摘要: A bearded needle (10) comprises a needle shank (10a) whose tip is shaped into a thin shank portion (10b) by tapering down the thickness of the needle shank (10a). The thin shank portion (10b) has a conical projection portion (12) at the extremity thereof. The conical projection portion (12) has a hooking tip portion (14) to form a hooking portion (13) at the tip of the needle shank (10a). The hooking portion (13) has a substantially U-shaped bottom portion (11) that hooks and holds a thread (S), and includes sloping surfaces (16) each inclining toward an outer edge (14a) of the hooking tip portion (14). The sloping surfaces (16) each extend from the bottom portion (11) over both the conical projection portion (12) and the hooking tip portion (14).
