PROBLEM TO BE SOLVED: To provide a supply apparatus for an object to be measured which is used for a seasoning apparatus for improving uniformity of the seasoning addition (the way of sprinkling a seasoning) to the object to be measured (a semi-finished product) compared to a conventional art.SOLUTION: The supply apparatus for an object to be measured includes: a vibrating feeder 10 for conveying the object to be measured by vibration； a reflecting type layer thickness measuring instruments 13A, 13B, 13C for measuring layer thickness of the object to be measured piling up in a layered shape on the vibrating feeder 10； a weighing conveyor 20 for measuring weight of the object to be measured when the object to be measured discharged from an end part of the vibrating feeder 10 is transported on a conveyor； and a controller 30 for controlling conveying speed of the object to be measured by the weighing conveyor 20 so that the layer thickness of the object to be measured on the weighing conveyor 20 is constant based on the layer thickness of the object to be measured.
