ABSTRACT:
A writing point assembly and an ink tube and/or a holder can be welded appropriately at a predetermined area without using ultrasonic waves, so as to be able to prevent dislodging of the writing point assembly, ink leakage and the like. The rear end part, of a metallic writing point assembly as a part of a writing instrument, is inserted into a joint, and is heated at the predetermined area (at least the fitted area in contact with the front end part of the joint), so as to weld the predetermined area of the writing point assembly to the surrounding part of the joint.
