PROBLEM TO BE SOLVED: To provide a low-cost garbage disposal device B capable of measuring the water content of an examined object and discriminating whether a metal piece is mixed in the examined object in a short time. SOLUTION: This garbage disposal device B with a water content measuring system A built inside, a metal piece detecting and water content computing part 73 extracts the water content from a correlation expression 811 by applying circuit currents Ia, Ib detected by a current detecting part 72 in the connected state of capacitors 51, 52, to inductance L-circuit current I characteristics 91, 92. In the case the extracted water content is in a range of 0%-100%, an actuator controller 3 controls an actuator 2 on the basis of the extracted water content. In the case the extracted content is outside the range, an alarm 31 is driven, determining the intrusion of a metal piece in the examined object.
