In a system for inspection of wood-board thickness, displacement sensors (2(21U, 22U, 23U, 21L, 22L, 23L)) are disposed at three positions with respect to a width of a wood material (1) being conveyed thereto for measurement of the thickness thereof. A programmable controller (6) determines the pass/fail of the board thickness based on the extent of portion having a board thickness deviated from the range of allowance extending along a conveyance direction.
