ABSTRACT:
In a surgical needle, marks of welding are left as they are on a welded portion between needle and pipe members so that the welded portion has a surface distinguishable from peripheral surfaces of the respective needle and pipe members. The welded portion may be composed of a plurality of peripherally spaced welded parts. In a manufacturing method of the surgical needle, a beam energy is applied from a beam energy emitting arrangement, toward an abutting line between the needle and pipe members, from a direction substantially perpendicular to the needle and pipe members, thereby welding them to each other.
