A sieving device includes a mount, and a vibration unit configured to perform reciprocating vibration relative to the mount in one direction in plan view and including a sieve frame. The vibration unit includes a first sensor unit and a vibration state measurement unit. The first sensor unit includes a vibration-unit acceleration sensing unit capable of sensing acceleration of the vibration unit, and a vibration-unit angular velocity sensing unit capable of sensing angular velocity of the vibration unit. The vibration state measurement unit measures a vibration state of the vibration unit based on the acceleration and the angular velocity of the vibration unit, which are sensed by the first sensor unit.
