Abstract
A dialysis catheter is provided which makes it possible to improve patency without reducing the ease of insertion, while also making it possible to effectively suppress the 'clinging phenomenon'. The dialysis catheter has a first portion provided with a thickened part which increases the thickness of the peripheral wall of a blood feed lumen on the blood removal lumen side thereof, and the cross-sectional area of the first portion is smaller than the cross-sectional area of a second portion.
