PROBLEM TO BE SOLVED: To provide a heating plate capable of ensuring good visibility while preventing generation of a light beam, and a window for a vehicle and a building including the heating plate.SOLUTION: A heating plate 10 includes a support base material 21, a pair of bus bars to which a voltage is applied, and a heating conductor 30 supported by the support base material 21 and connected with the pair of bus bars. The heating conductor 30 has a conductive main fine line 31 extending between the pair of bus bars. Each conductive main fine line 31 includes a first large curvature portion 31b having a relatively large curvature, and a first small curvature portion 31a having a relatively small curvature. A slope of a cross-section of the first large curvature portion 31b in a cross-section of the conductive main fine line is larger than a slope of a cross-section of the first small curvature portion 31a.SELECTED DRAWING: Figure 5
【課題】光芒の発生を防ぎつつ、良好な視界を確保できる発熱板、及びそのような発熱板を備える乗り物及び建築物用窓を提供する。【解決手段】発熱板10は、支持基材21と、電圧が印加される一対のバスバーと、支持基材21に支持され一対のバスバーに接続される発熱用導電体30とを備える。発熱用導電体30は、一対のバスバー間に延在する導電性主細線31を有する。各導電性主細線31は、曲率が相対的に大きい第1の大曲率部分31bと、曲率が相対的に小さい第1の小曲率部分31aとを含む。導電性主細線の横断面のうち第1の大曲率部分31bの横断面の傾きは、第1の小曲率部分31aの横断面の傾きよりも大きい。【選択図】図5
