The indwelling position can be clearly imaged with X-rays, and the indwelling position can be easily confirmed even if the opaque X-ray line is omitted. In addition, since the tip member and the main tube can be melted and connected within the mold,
A seamless connection is created. Furthermore, since the tip member can be molded with a mold, the chamfered shape can be made uniform, and mass production becomes possible.
