    Abstract: A first object of the present invention is to provide a transfer film that is capable of forming a resist pattern having excellent resolution. In addition, a second object of the present invention is to provide a transfer film that is capable of forming a resin pattern having excellent planarity. Further, a third object of the present invention is to provide a manufacturing method for a laminate, a manufacturing method for a circuit wire, and a manufacturing method for an electronic device, using the above-described transfer film.
    The transfer film of the present invention is a transfer film having a temporary support and a composition layer disposed on the temporary support, in which the composition layer includes a photosensitive resin layer and a water-soluble resin layer, where the transfer film is obtained by laminating the temporary support, the water-soluble resin layer, and the photosensitive resin layer in this order or obtained by laminating the temporary support, the photosensitive resin layer, and the water-soluble resin layer in this order.
    The water-soluble resin layer contains a compound A having a group represented by General Formula (1).





    In the formula, * represents a bonding position.
