Provided are a planar heating element and a vehicle windshield device that can effectively suppress adhesion of foreign matter. The planar heating element is provided with: a heating wire which is repeatedly folded back so as to cover a surface surrounded by an outer contour line; and a conductive wire for supplying a current to the heating wire, the conductive wire following the outer profile by having a width greater than the width of the heating wire and a lower resistivity than the heating wire.
提供能够有效地抑制异物附着的面状发热体及车辆用挡风玻璃装置。面状发热体具备:发热线,以将被外廓线包围的面覆盖的方式反复折回;和导线,用于向所述发热线供给电流,通过具有比所述发热线的宽度大的宽度而具有比所述发热线低的电阻率,追从所述外廓线。
