This creation is a kind of deflection single-side heating device, including at least having: a heat insulation layer is to be made of the heat-insulating material of deflection； One heating layer is to be stacked on heat insulation layer, which is the metal wire of conduction, which is in be electrically connected with a power input； One flexible metallic layer is set on the what heating layer, is to be made of the metal foil membrane body of deflection, is had along the flexible metallic layer plane direction conductive force. In addition, with insulating layer isolation among the heating layer and the flexible metallic layer； So, by blocking for the heat insulation layer, conduct major part heat source caused by heating layer only can to the flexible metallic layer unidirectionally, not only make that heat source is uniformly spread and heat transfer is rapid, the efficiency that heats up is twice of general twocouese heating, so that heat insulation effect is reached more preferable benefit, and be all made of bendable material by each layer, the single-side heating device is made to have deflection characteristic.本創作係一種可撓曲單面發熱裝置，至少包括有：一絕熱層，係由可撓曲之絕熱材料所構成；一發熱層，其係疊置在絕熱層上，該發熱層係為導電之金屬線，該發熱層與一電源輸入端呈電連接；一可撓曲金屬層，其設於該發熱層上，係由可撓曲之金屬薄膜體所構成，具有沿該可撓曲金屬層平面方向導熱作用。另，該發熱層與該可撓曲金屬層中間以一絕緣層隔絕；如此，藉由該絕熱層之阻絕，使發熱層所產生的大部分熱源僅會向該可撓曲金屬層單向傳導，不但使熱源均勻擴散、且熱傳導迅速，升溫效率為一般雙方向加熱之兩倍，使保溫效果達到更好效益，且藉由各層皆由可撓曲材料構成，使該單面發熱裝置具可撓曲特性。
