A reflow method includes preparing a to-be-processed object, which includes a first layer, a second layer formed in an upper layer to the first layer, and a resist film, which is directly on the second layer and has a pattern allowing formation of an exposure region in which the first layer is exposed and a coverage region in which the first layer is covered, wherein said resist film has an end thereof protruding out further above the exposure region than the edge of the second layer. The resist film has a shape protruding out further above the exposure region than the edge of the second layer. The method also includes covering a part or all of the exposure region by softening and reflowing the resist film.
