Tip with encapsulated marker band

[Subject] Provide a catheter chip assembly object including the chip provided with the enclosed marker band, and a manufacturing method for the same. [Means for Solution] A catheter chip assembly object consists of a marker band and a catheter chip, A catheter chip demarcates inner 腔 which penetrates the inside, while the catheter chip consists of a lateral part and an inner portion, a marker band is arranged between the lateral part and the inner portion, and a lateral part is united with an inner portion so that it may enclose a marker band. A process which the manufacturing method provides with a core pin, and a process of arranging a polymer tube around a core pin, Before fabricating a catheter chip and cooling on a process of arranging a marker band around a polymer tube, a process of fusing material for a catheter chip, and a marker band and a polymer tube, a process of uniting fusion material for a catheter chip with a polymer tube is included.
