Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a tether measuring device capable of measuring the tension and the rate of stretch of a tether, even in a case where it is difficult to bring a sensor unit into contact with the tether because of the materials or the like of the tether, and so on. SOLUTION: The tether measuring device for measuring the tension and/or the rate of stretch of the tether 10 includes a light source 12a, a light receiving part 12b, and a signal processing part 13. The light source 12a emits sheetlike light L, and is arranged so that the tether 10 passes through an area to which the sheetlike light L is emitted; the receiving part 12b receives the sheetlike light L and outputs a received light signal; and the processing part 13 gets an input of the received light signal, and from the received light signal calculates the tension and/or the rate of stretch of the tether 10.
