PURPOSE: An inspection device of a spread status on a window glass is provided to precisely inspect a starting point and a finishing point. CONSTITUTION: A reference line is set by deciding reference points 1, 2 about an initial tested good having a fine spread status of a window glass. In obtaining a photographed image of the spread status through a photographing unit(S410), finishing points of each cell are calculated by dividing an inspection area of the spread status to many sub cells(S420). The ratio which many finishing points are under the reference line is calculated(S430). A spread amount of a sealer on the window glass is decided as a lack or a non-spread status(S450) when the ratio is over a set value(S440). Thereby, the starting point and the finishing point are inspected precisely and an inspection device is simplified.
