PROBLEM TO BE SOLVED: To provide a method for inspecting application uneveness, which effectively detects the uneven application of a transparent resin coat. SOLUTION: The method comprises forming a number of small regions by carrying out a dividing operation along the direction of application of the transparent resin and the direction perpendicular thereto; irradiating these small regions with light; measuring intensity values of reflected light for respective small regions; defining the direction of application or the direction perpendicular thereto as an accumulation direction; calculating a reference accumulated value, by accumulating the intensity values of reflected light of small regions aligned along the accumulation direction in a reference area 51; further, defining the direction of application or the direction perpendicular thereto as accumulation direction; calculating the accumulated value by accumulating the intensity values of reflected light of small regions aligned along the accumulation direction in a scanning area 52 inside the reference area 51; calculating variance values at a prescribed interval from the accumulated value and the reference accumulated value; and extracting the application uneveness by comparing variance values of the reference area 51 and the scanning area 52.
