摘要：Problem to be solved: to provide a catheter and a method of manufacturing acatheter capable of maintaining the junction strength of a resin material having adifferent hardness at the distal and proximal sides, and effectively suppressing theseparation of the junction. An internal catheter (30) used in conjunction with said guidingcatheter (20), which can be pulled out into the lumen of the guiding catheterDistaltubular (71) made of resin located on the distal sideIt is made of resin with a higherhardness than the distal tubular partA proximal tubular portion (72) coupled to theproximal end of distal tubular portion (71) and distal endAndThe distal end of theproximal tubular portionThe tapered portion (75) located in the radial direction of thedistal tubular portion (71) gradually decreasing toward the distal side and graduallydecreasingHaving a cover (76) surrounding the radially outward portion of the proximal

end portion of the distal tubular portion (71) projecting from the proximal portion of thetapered portion (75) to the distal side;Distal tubular sectionIt has a wedge portion (77)sandwiched between the tapered portion (75) and the covering portion (76).
