Abstract

A transfer film includes a temporary support; and a photosensitive layer, in which the photosensitive layer includes a polymer A containing a constitutional unit represented by Formula A1, a constitutional unit derived from a monomer having an alicyclic structure, and a constitutional unit having a radically polymerizable group, a radically polymerizable compound, and a photopolymerization initiator, a content of the constitutional unit represented by Formula A1 is 10% by mass or more with respect to a total mass of the polymer A, a content of the constitutional unit derived from the monomer having the alicyclic structure is 15% by mass or more with respect to a total mass of the polymer A, and a glass transition temperature of a homopolymer of the monomer having the alicyclic structure is 120° C. or higher.
