摘要： PROBLEM TO BE SOLVED: To measure the thickness of paint in a state before drying and hardening with high accuracy without contact independently of the type of an object to be measured and the paint, by measuring the distance from a reference surface to a body to be painted before painting and the distance from the reference surface to the paint surface after painting through the use of laser displacement meters, and computing the difference between both measured distances. SOLUTION: A reference surface is placed on the same circumferential surface at a predetermined distance from the center of a packing roll 2, the locations of a steel plate S in coil before painting and a steel plate S' in coil after painting on the packing roll 2 from the reference surface are each measured by laser displacement meters 11 and 12. The surface location of the steel plate S' after painting captured by the laser displacement meter 12 is changed by the thickness of the paint film with respect to the location of the steel plate S before painting captured by the laser displacement meter 11. Therefore, by measuring the distance L1 from the reference surface to a body to be painted before painting and the distance L2 from the reference surface to the paint surface after painting, inputted them to a paint film thickness computing means 21 to compute L2-L1, and displaying the result of the computation on a paint film thickness displaying means 22, the thickness of the paint film is obtained.
