PROBLEM TO BE SOLVED: To simplify a manufacturing process, in a heat transport device, a method of manufacturing the heat transport device, and an electronic apparatus.SOLUTION: A method of manufacturing a heat transport device comprises the steps of: forming metallic layers 22 on each of surfaces of two sheets of resin sheets 21 at least one of which is transparent; welding the metallic layers 22 of the resin sheets 21 by applying laser L to the metallic layers 22 at an edge of a region R on which a flow channel 25 is to be formed, through the transparent resin sheet 21 while keeping the metallic layers 22 of two sheets of resin sheets 21 into closely contact with each other; vertically separating the resin sheets 21 of unwelded parts by applying force F from the side of two sheets of resin sheets 21 after welding the metallic layers 22, to define the part as the flow channel 25; and encapsulating a working liquid C into the flow channel 25.SELECTED DRAWING: Figure 6 【課題】熱輸送デバイス、熱輸送デバイスの製造方法、及び電子機器において、製造工程を簡略化すること。【解決手段】少なくとも一方が透明な二枚の樹脂シート２１の各々の表面に金属層２２を形成する工程と、二枚の樹脂シート２１の各々の金属層２２同士を密着させながら、流路２５を形成する予定領域Rの縁における金属層２２に透明な樹脂シート２１を介してレーザLを照射することにより、樹脂シート２１の各々の金属層２２同士を溶着する工程と、金属層２２同士を溶着した後、二枚の樹脂シート２１に横から力Fを加えて未溶着の部分における各々の樹脂シート２１を上下に離し、当該部分を流路２５にする工程と、流路２５に作動液Cを封入する工程とを有する熱輸送デバイスの製造方法による。【選択図】図６
