The intermediate formed article has a first intermediate positive surface that corresponds to the site extending from the ridge section to the negative surface of the target formed article and also has a second intermediate positive surface that corresponds to the site extending from the ridge section to the positive surface of the target formed article and that continues from the first intermediate positive surface and an intermediate negative surface continuing from the second intermediate positive surface.
