  • a plurality of wired circuit boards;

    defect-distinguishing marks which distinguish defectiveness of the wired circuit boards; and

    a supporting sheet for supporting the plurality of wired circuit boards and the defect-distinguishing marks,wherein each of the defect-distinguishing marks comprises an indication portion for indicating a specified wired circuit board,wherein the defect-distinguishing marks are not attached to the wired circuit boards;

    wherein each of the defect-distinguishing marks is provided on the supporting sheet in a spaced-apart relation from the specified wired circuit board corresponding to said each defect-distinguishing mark, and the indication portion indicates the specified wired circuit board from external of the specified wired circuit board; and

    wherein the indication portion has a shape tapered toward an indication direction indicating the specified wired circuit board, so as to distinctly represent a correspondence between a particular defect-distinguishing mark and the specified wired circuit board by directing the indication direction of the indication portion toward the specified wired circuit board to thereby identify a defective wired circuit board from among the plurality of wired circuit boards supported on the supporting sheet.
