The present invention provides a coating method including: a step of supplying a coating agent to a surface of a lens base material; a spreading step of spreading the coating agent supplied to the surface by rotation of the lens base material; a first removal step of removing at least a part of a liquid pool of the coating agent generated on a peripheral edge portion and/or a side surface portion of the lens base material by rotation of the lens base material after the spreading step; and a second removal step of removing the liquid pool remaining on the peripheral edge portion and/or the side surface portion of the lens base material by bringing an adsorption member into contact with at least the side surface of the lens base material after the first removal step. According to the present invention, it is possible to provide a coating method capable of obtaining a base material having a coating layer excellent in uniformity of film thickness by reducing the liquid pool of the coating agent generated on the peripheral edge portion and/or the side surface portion of the lens base material when the coating layer is formed on the surface of the base material by spin coating the coating agent.
