To shorten the time required for foil transfer.SOLUTION: A foil transfer method includes: a first superposing step S100 for superposing an object to be transferred W1 on a supporting stand 40, and also superposing a thermal transfer foil W2 on the object to be transferred W1; a second superposing step S200 for superposing a photothermal conversion body W3 having a photothermal conversion part W31 that absorbs light L and converts it to heat and a non-photothermal conversion part W32 that is a part other than the photothermal conversion part W31 on the thermal transfer foil W2; and a foil transfer step S300 for irradiating the a photothermal conversion body W3 from above the photothermal conversion body W3 with the light L, and transferring a part of the thermal transfer foil W2, which superposes on the photothermal conversion part W31 to the object to be transferred W1. In the foil transfer step S300, the photothermal conversion body W3 is irradiated with the light L, whose irradiation shape is line-like.SELECTED DRAWING: Figure 4 【課題】箔転写に要する時間を短縮する。【解決手段】箔転写方法は、支持台４０の上に被転写物Ｗ１を重ね、かつ、被転写物Ｗ１の上に熱転写箔Ｗ２を重ねる第１重ね工程Ｓ１００と、光Ｌを吸収して熱に変換する光熱変換部Ｗ３１と、光熱変換部Ｗ３１以外の部分の非光熱変換部Ｗ３２とを有する光熱変換体Ｗ３を熱転写箔Ｗ２上に重ねる第２重ね工程Ｓ２００と、光熱変換体Ｗ３の上方から光熱変換体Ｗ３に向かって光Ｌを照射して、光熱変換部Ｗ３１と重なる熱転写箔Ｗ２の部分を被転写物Ｗ１に転写する箔転写工程Ｓ３００と、を包含する。箔転写工程Ｓ３００では、照射形状がライン状の光Ｌを光熱変換体Ｗ３に向かって照射する。【選択図】図４
