Abstract: In a transfer foil, a transfer material layer and a support body for releasably supporting the transfer material layer are laminated. A first release strength at a first temperature when the transfer material layer is released from the support body is 0.1 gf/mm or more and 0.3 gf/mm or less. A difference between the first release strength and a second release strength at a second temperature that is higher than the first temperature and lower than a transfer temperature when the transfer material layer is released from the support body is 0.05 gf/mm or more and 0.2 gf/mm or less.
