PROBLEM TO BE SOLVED: To improve visibility through a heating plate having a heating conductor.SOLUTION: When a voltage is applied, a heating conductor 30 generates heat and includes a plurality of linear conductors 31 arranged in a pattern to form a plurality of openings 35. The linear conductor 31 includes: an intersection part 34 for intersecting with other linear conductors; a linear part 32 which extends independently from other linear conductors; a widened part 33 for widening the width of the linear conductor 31 between the intersection part 34 and the linear part 32. The widened part 33 of the linear conductor 31 shares a part thereof together with the widened part of other linear conductors intersecting with the linear conductor. In a contour of the widened part 33, the radius of curvature includes a curved part 33a of 15 μm or more and 60 μm or less. The distance between centers of gravity of openings 35 adjacent to each other is 250 μm or more and 1500 μm or less. The width of the linear part 32 is 2 μm or more and 15 μm or less. The width of the linear conductor 31 is 1 μm or more and 30 μm or less.SELECTED DRAWING: Figure 5

    【課題】発熱用導電体を有する発熱板を介した視界を良好にする。【解決手段】発熱用導電体30は、電圧を印加されると発熱し、複数の開口部35を形成するパターンで配置された複数の線状導電体31を備える。線状導電体31は、他の線状導電体と交差する交差部34と、他の線状導電体とは独立して延びる線状部32と、交差部34と線状部32の間において線状導電体31の幅を拡幅させる拡幅部33と、を有する。線状導電体31の拡幅部33は、当該線状導電体と交差する他の線状導電体の拡幅部と、その一部を共有している。拡幅部33の輪郭は、曲率半径が15μm以上60μm以下の曲線部33aを含む。隣り合う開口部35の重心間距離は、250μm以上1500μm以下である。線状部32の幅は、2μm以上15μm以下である。線状導電体31の厚さは、1μm以上30μm以下である。【選択図】図5
