To provide a coating-state inspection method capable of acquiring accurate inspection results of a coating state of a coated object even if a viscous material includes a material with high wettability and spreadability or a material likely to cause irregular light reflection.
The coating-state inspection method includes: capturing an image of a paste Pst applied on a substrate Pb in a predetermined painting pattern, and acquiring the image (step ST1); extracting a contour G of the paste Pst applied on the substrate Pb based on the acquired image (step ST2); determining the contour length of the paste Pst based on the extracted contour G of the paste Pst (step ST3); comparing the determined contour length of the paste Pst and the reference range of the contour length determined according to the painting pattern of the paste Pst and determining whether the contour length of the paste Pst is within the reference range (steps ST4 to ST6); and determining the quality of the coating state of the paste Pst (steps ST7 and ST8).
