Zusammenfassung:	A sheath core assembly, a method for manufacturing a sheath core assembly, and a delivery device are provided. The sheath core assembly includes a sheath core (11), and a tip (14) and a connector which are provided at a distal end of the sheath core (11). The tip (14) includes a first connecting section (141) and a guiding section (142) coaxially connected to a distal end of the first connecting section (141). The guiding section (142) is tapered and has an outer diameter gradually decreasing from a proximal end to a distal end thereof. The connector is connected between the sheath core (11) and the tip (14). A proximal end of the connector extends out from a proximal face of the tip (14), and a distal end of the connector extends towards a distal end of the tip (14) and forms an extending section (122). The extending section (122) is embedded in the guiding section (142). The extending section (122) is tapered and has an outer diameter gradually decreasing from a proximal end to a distal end thereof. The problems of difficult cleaning and breakage of a tip (4') of an existing delivery system caused by bubbling in injectionmolding of the tip (4') can be solved.
