PROBLEM TO BE SOLVED: To provide a measuring device or the like capable of easily measuring a position of an object, such as an excavator body.SOLUTION: A measuring device 1 measures a position of an excavator body 6 in excavation of a ground 7, is constituted by vertically connecting a plurality of rod-shaped measurement units 10, and measures a position of the excavator body 6 mounted to one end part. The measurement unit 10 includes: an inclination measuring device that is a casing including a cavity in the inside and measures inclination of the measurement unit 10; and an antenna member for transmitting a measurement result to the inclination measuring device. In a connection place for connecting the upper and lower measurement units 10, the upper and lower measurement units 10 can be relatively rotated. The connection place includes a connection place in which the upper and lower measurement units 10 are relatively rotatable at least within a predetermined surface, and a connection place in which the upper and lower measurement units 10 are relatively rotatable within a surface orthogonal to at least a predetermined surface.SELECTED DRAWING: Figure 1
