PROBLEM TO BE SOLVED: To provide an ultrasonic square sieve device which sorts resin carbonized matter and metal powder from a mixture of resin and metal powder using an ultrasonic transducer, can suppress heat generation of attaching part of the ultrasonic transducer even if a power source of a large capacity is used, and can secure sufficient ultrasonic vibration and fluidity of powder of a collection part (trough part), even if a vibration frame of a large area is used. SOLUTION: This ultrasonic square sieve device sorts resin carbonized matter and metal powder from the mixture of resin and metal powder using the ultrasonic transducer, and has holes near the ultrasonic transducer in the vibration frame for attaching the ultrasonic transducer.
