PROBLEM TO BE SOLVED: To provide a weight measuring apparatus 100 capable of accurately measuring the weight of a workpiece 5.SOLUTION: A weight measuring apparatus 100 for measuring a weight W of a workpiece 5 is constituted by a plurality of members having a different sectional area from each other, and includes: a supporting member 20 for supporting the workpiece 5; an electronic balance 60 for measuring the weight W of the workpiece 5 on the basis of a load which is made to act thereon by the supporting member 20; pressure sensors 51, 52, 53, and 54 for detecting an atmospheric pressure at portions having the varying sectional area in the supporting member 20; and a controller 50 for correcting the weight W of the workpiece 5 measured by the electronic balance 60 on the basis of the atmospheric pressures, detected by the pressure sensors 51, 52, 53, and 54, around the portions having the varying sectional area in the supporting member 20. |
