The surface profile of a coating material in a substrate width direction is optimized in coating a substrate with the coating material such as an electrode active material. A gap adjuster configured to adjust a gap between a nozzle for ejecting a coating material and a substrate to be coated with the coating material, a rotation speed adjuster configured to adjust a rotation speed of a pump for pressure-feeding the coating material to the nozzle, a model calculator configured to calculate a surface profile of the coating material based on an end region model and a central region model wherein the end region model models profiles of rising regions in the surface profile of the coating material in a width direction of the substrate and the central region model models a profile of a central region between the rising regions in the surface profile, a comparator configured to compare a predetermined set profile with the surface profile of the coating material calculated by the model calculator, and a control calculator configured to calculate a control amount of at least one of the gap adjuster and the rotation speed adjuster based on a comparison result of the comparator are included.
