Abstract
A wiring circuit board assembly sheet is partitioned by a product region in which a plurality of wiring circuit boards serving as products are disposed in alignment and a margin region surrounding the product region with the margin region having a first area adjacent to the product region and a second area located at the opposite side of the product region with respect to the first area. The wiring circuit board assembly sheet includes a dummy wiring circuit board disposed in at least a portion of the first area and smaller than the wiring circuit board.
