A medical manipulator including: a rotating joint that rotates an end effector disposed at a distal end thereof about a first axis a flexing joint that is disposed on a base-end side of the rotating joint and that pivots the end effector about a second axis that intersects the first axis a drive portion that generates a rotational driving force a motive-power transmitting member that transmits the rotational driving force generated by the drive portion to the rotating joint by passing through the flexing joint and a speed-reduction portion that transmits the rotational driving force transmitted thereto by the motive-power transmitting member to the end effector after performing speed-reduction.
