The present invention relates to an optothermal fibre sheet which converts light such as sunlight into heat energy and is outstandingly thermally efficient; wherein a heat-emitting area in the form of a dot or line pattern is formed together with a non-heat-emitting area that does not overlap the heat-emitting area on one surface of a fabric, and wherein, in the heat-emitting area, a non-heat-emitting area in the form of a dot or line pattern is constituted by carbon nanotubes (CNT) or a group 4 metal carbide on one surface of the fabric. |
