The present invention includes a current plate which is arranged above a substrate in a chamber. A pressure inside the chamber is reduced by exhaust means and drying processing is performed on, for example, a coating solution on the substrate. On a peripheral portion of an underneath surface of the current plate, formed is a ring-shaped protrusion corresponding to a peripheral portion of the substrate. A protruding portion of a coating solution at the peripheral portion of the substrate is made flat by air current generated when the pressure is reduced, and consequently a coating film with a uniform film thickness as a whole is formed on the substrate.
