Abstract: Provided is a method for manufacturing a transfer sheet which can impart a sufficient function to an adherend. The method for manufacturing a transfer sheet includes performing the following steps (1) and (2) in order: (1) applying a coating liquid for forming a transfer layer onto a release substrate 1 to form a transfer layer comprising at least one functional layer; and (2) laminating a release substrate 2 onto the transfer layer to obtain a transfer sheet A comprising the release substrate 1, the transfer layer and the release substrate 2 in the presented order and having a peel strength 2 between the release substrate 2 and the transfer layer larger than a peel strength 1 between the release substrate 1 and the transfer layer.
