Abstract: Aboard inspection device includes: an imaging device that takes an image of an area on the board where the adhesive is applied; a CPU that specifies, by a first procedure, a center portion area of the adhesive in the image; specifies, by a second procedure, a foot portion area of the adhesive around the center portion area in the image; specifies an entire area of the adhesive based on the center portion area and the foot portion area; and based on the entire area of the adhesive, determines whether a quality of the adhesive is good or poor. The adhesive has a red color and is applied on a green resist area, and when specifying the foot portion area, the CPU extracts, an area of lower saturation than a predetermined saturation reference value from a saturation image based on the image.
