PROBLEM TO BE SOLVED: To perform the conditioning of optimum transfer pressure with a high degree of accuracy by minimizing a time loss and a material loss. SOLUTION: In this thermal transfer method, the relational expression, which represents a correlation between the transfer pressure and a distance L between a surface plate 14 and a hot plate 12, is derived, and an L-value is calculated from the required transfer pressure, so that the height position of the surface plate 14 can be set. Additionally, a displacement measuring unit 50 including a dial gauge 51 is mounted between the surface plate 14 and a pedestal part of a pressing machine, and the proper transfer pressure is maintained/controlled by monitoring variations in the height position of the surface plate 14, so that a high-quality transfer foil-stuck state can be ensured.
