[Problem] To provide a manipulator and manipulator system that have a small number of parts and a simple structure, and can be assembled easily and operated smoothly. [Solution] A manipulator (1) is provided with an operating part (2b) and a bending section (4) that bends as a result of operation of the operating part (2b) and is characterized in that the bending section (4) is provided with: first link members (11) with a first arc-shaped section (11a)； second link members (12) with a second arc-shaped section (12a)； intermediate link members (13) attached between the first link members (11) and the second link members(12)； first connecting members (21) for connecting the first link members (11) to the intermediate link members (13)； second connecting members (22) for connecting the second link members (12) to the intermediate link members (13)； and regulating members (30), which are wound so as to intersect between the first arc-shaped sections (11a) of the first link members (11) and first intermediate arc-shaped sections (13a) of the intermediate link members (13) and wound so as to intersect between the second arc-shaped sections (12a) of the second link members (12) and second intermediate arc-shaped sections (13b) of the intermediate link members (13), and which regulate the members so that the first arc-shaped sections (11a) roll and rotate with respect to the first intermediate arc-shaped sections (13a), and the second arc-shaped sections (12) roll and rotate with respect to the second intermediate arc-shaped sections (13b).Le problème posé par l'invention concerne la fourniture d'un manipulateur et d'un système de manipulateur qui aient un petit nombre de pièces et une structure simple et qui puissent être montés facilement et opérés de manière souple. La solution de l'invention porte sur un manipulateur (1) doté d'une pièce d'opération (2b) et d'une section de flexion (4) qui fléchit en résultat de l'opération de la pièce d'opération (2b) et caractérisé e
