    Abstract: A coating method includes supplying a film forming liquid onto a center of a front surface of a substrate from a nozzle in a state that a distance between the front surface and the nozzle is maintained at a coating distance; rotating the substrate at a first rotation speed in a period during which the film forming liquid is supplied onto the front surface, to allow the film forming liquid to be diffused toward an edge of the substrate from an outer periphery of the nozzle; and rotating the substrate at a second rotation speed after the supplying of the film forming liquid is stopped, to allow the film forming liquid to be further diffused. The coating distance is set to allow the film forming liquid to be kept between the nozzle and the front surface when a discharge of the film forming liquid is stopped.
