Abstract: A transfer sheet including a support layer including a porous material, and a thin-film layer supported by the support layer and having a thickness of 5000 nm or less. The transfer sheet has a dry adhesion strength of 100 mN or more, and a wet adhesion strength of lower than the dry adhesion strength and 230 mN or less, where the dry adhesion strength is an adhesion strength between the support layer and the thin-film layer while the support layer and the thin-film layer are dry, and the wet adhesion strength is an adhesion strength between the support layer and the thin-film layer while the support layer and the thin-film layer are wet.
