PROBLEM TO BE SOLVED: To provide a weighing apparatus which can improve the inspection precision of resin products. SOLUTION: The total weight of a plurality of the resin products is set up to be a standard value, and the first upper limit side threshold and the first lower limit side threshold are set up on the upper limit side and lower limit side of the standard value respectively and stored in a control circuit 38. The second upper limit side threshold which is larger than the first upper limit side threshold and the second lower limit side threshold which is smaller than the first lower limit side threshold are stored in the control circuit 38. When the total weight is larger than the first upper limit threshold, it is judged by the circuit 38 whether the total weight is larger than the second upper limit side threshold or not. When the total weight is smaller than the lower limit side threshold, it is judged by the circuit 38 whether the total weight is smaller than the second lower limit side threshold or not.
