To provide a planar heating element capable of improving the responsibility of rising temperature, and to provide a vehicle windshield device.SOLUTION: Disclosed is a planar heating element which includes a planar heat generation part composed of a linear heating element. The heat generation part 22 includes: a first heat generation part 221 located along the periphery of an object region to be heated; and a second heat generation part 222 located in the region surrounded by the first heat generation part 221. The second heat generation part 222 includes a plurality of line segments, each of which has a meandering shape. The line segments adjacent to each other meandering in one direction are superimposed in the meandering direction. In the heat generation part 22, a width WL of the linear heating element is larger than a width WP between linear heating elements adjacent to each other.SELECTED DRAWING: Figure 5
【課題】昇温の応答性を向上可能とした面状発熱体、および、車両用ウインドシールド装置を提供する。【解決手段】線状発熱体から構成される面状の発熱部を備えた面状発熱体であって、発熱部22は、加熱される対象領域の周縁に沿って位置する第1発熱部221と、第1発熱部221に囲まれた領域に位置する第2発熱部222と、を備え、第2発熱部222は、蛇行状を有した複数の線分を備え、1つの方向に向けて蛇行する相互に隣り合う線分同士が、蛇行する方向で重畳しており、発熱部22において、線状発熱体の幅WLは、相互に隣り合う線状発熱体の間の幅WPよりも大きい。【選択図】図5
