A coating apparatus includes: a slit nozzle that discharges a coating material from a discharge port in a slit shape; a moving mechanism that relatively moves the slit nozzle with respect to a substrate in a disk shape; and a control unit that controls the moving mechanism, wherein the control unit performs a first constant speed coating treatment of relatively moving the slit nozzle with respect to the substrate at a first speed, then an acceleration coating treatment of accelerating a relative moving speed of the slit nozzle with respect to the substrate to a second speed higher than the first speed, and then a second constant speed coating treatment of relatively moving the slit nozzle with respect to the substrate at the second speed.
