Abstract

Provided is a state determination device and a state determination method for a ball screw capable of improving noise resistance. Included are: a vibration information generating unit (201) that generates vibration information indicating a relationship between a nut position of the ball screw and a frequency-vibration level characteristic that varies depending on to the nut position on the basis of a vibration signal acquired by a vibration sensor (21) during operation of the ball screw; and a determination unit (202) that executes state determination processing of the ball screw on the basis of first vibration information generated on the basis of a vibration signal acquired in a first period and second vibration information acquired in a second period after the first period.
