PROBLEM TO BE SOLVED: To provide a catheter and catheter operation part a bending operation part of which is reliably operated even in a state where a syringe is mounted on a hub connector.SOLUTION: A catheter operation part 50 includes a bending operation part 60, a hub connector 70, an operation part body 80, and a reinforcement member 90. The bending operation part 60 pulls operation wires so as to bend the distal part of a catheter. The bending operation part 60 has engagement parts with the proximal end parts of the operation wires and gives pulling force to the multiple operation wires individually by a pulling operation. The hub connector 70 has a through-hole communicating with the main hollow part of the tubular body and a syringe is mounted on the hub connector. The operation part body 80 includes an upper side body 82 and a lower side body 84 for holding the bending operation part 60 and the hub connector 70 between them, and houses the proximal end part of the tubular body. The reinforcement member 90 is mounted around the hub connector 70, the upper side body 82, and the lower side body 84, so as to suppress the separation of the upper side body 82 and the lower side body 84.【課題】ハブコネクタにシリンジを装着した状態でも屈曲操作部を確実に操作することが可能なカテーテルおよびカテーテル操作部を提供する。【解決手段】カテーテル操作部５０は、屈曲操作部６０、ハブコネクタ７０、操作部本体８０および補強部材９０を備える。屈曲操作部６０は、操作線を牽引してカテーテルの遠位部を屈曲させる。屈曲操作部６０は、操作線の基端部との係合部を有し、牽引操作により複数本の操作線に個別に牽引力を付与する。ハブコネクタ７０は、管状本体の主管腔と連通する通孔を有し、シリンジが装着される。操作部本体８０は、屈曲操作部６０およびハブコネクタ７０を挟持する上側本体８２および下側本体８４を含み、管状本体の基端部を収容する。補強部材９０は、ハブコネクタ７０、上側本体８２および下側本体８４の周囲に装着されて、上側本体８２と下側本体８４との分離を抑制する。【選択図】図６
