A manipulator includes a manipulation body having a plurality of bar-shaped portions which intersect orthogonally with each other at one intersection point, and a plurality of detection bodies which detect a displacement of the manipulation body. The plural bar-shaped portions include a bar-shaped portion and another bar-shaped portion which intersect orthogonally with each other. The plural detection bodies include a first detection body which detects a displacement of one end side of the bar-shaped portion with respect to the intersection point, a second detection body which detects a displacement of the other end side of the bar-shaped portion with respect to the intersection point, and a third detection body which detects a displacement of one end side of the bar-shaped portion with respect to the intersection point.
