PROBLEM TO BE SOLVED: To provide a (1/n) power multiplying device having excellent precision by a simple circuit. SOLUTION: The (1/n) power multiplying device is provided with a divider 10 wherein a signal Z is inputted to an input terminal 10b, a signal X is inputted to an input terminal 10a, and a division result is outputted from the an output terminal 10c, an (n-2) power multiplier 14 for outputting a multiplication result obtained by multiplying the division result (n-2) times, and a coefficient multiplier 11 to constitute a negative feedback system, and obtains a signal corresponding to the (1/n) power of the signal X on the basis of an output signal from the divider.
