Claim:
1. A method for forming a conductive film, comprising: applying a composition on a substrate to form a coating film, wherein the composition comprises an acid generator and a polymer which comprises an acid dissociable group; irradiating a portion of the coating film with radiation; heating the coating film after the irradiating such that at least part of the portion of the coating film is evaporated and that a concave pattern is formed on the substrate; and applying a composition for conductive film formation on the substrate having the concave pattern to form the conducting film, wherein the concave pattern is formed without using a development of the coating film, and wherein a difference between a contact angle with respect to tetradecane of the irradiated portion of the coating film and a contact angle with respect to tetradecane of a portion of the coating film other than the irradiated portion is 30° or more.
