PROBLEM TO BE SOLVED: To properly determine the quality of a work.SOLUTION: An extraction device comprises: a calculation unit that calculates a range row 37 in time series by using a plurality of first data rows 30 in time series output by a sensor when a first work is performed to a plurality of first objects to be good ones in first quality determination; an extraction unit that extracts sections in which a second data row in time series, which is output by the sensor when the first work is performed to a second object to be a defect one in the first quality determination, is out of the range row, among a plurality of first sections 50a-50g into which the period of the first data rows is divided in time series, as second sections 56a, 56b for performing second quality determination in the first work. |
