The catheter includes a tubular body (12) made of an elastic and flexible synthetic resin material. The catheter is equipped with a valve (B 1) having a slit (16) that can be opened and closed passing through the outer surface (12b) of the tubular body from the inner surface (12a) of the tubular body. The catheter is also provided with the movable wall (15) sunken towards the inside of the tubular body (12) at an end tip member region (14) of the tubular body (12). The location where the movable wall (15) exists has a structure with differences in hardness in the thickness direction of the tubular body (12). In the cross-sectional surface perpendicular to the center axis (Cl) of the tubular body (12), the movable wall (15) has a wall central member (P1) located at a position close to the center axis (Cl) and a movable wall tip member (P2) located at a position far from the center axis (C1). The slit (16), is formed on the movable wall tip member (P2).2/4 [Figure 3] 16 16 15 12 15 12 12b 12b P1 P2 12a 15a 15b P1 P2 12 15a 15b (a) (b) [Figure 4] 21 BI 15b 15A 16 .P2 PI P2 15a 1 12 12a 12b
