PROBLEM TO BE SOLVED: To provide a technique which suppresses the rising of thermal stress in the neighborhood of an edge part of a glass plate even when a thermal line part is separated from the edge part of the glass plate.SOLUTION: A vehicular window glass is provided with a conductive filament part which is formed with a glass plate and a conductive material and is arranged on any surface of the glass plate. Therein, the conductive filament part includes a thermal line part which is separated from an end part of the glass plate and is arranged and has a prescribed pattern so as to heat a predetermined area of the glass plate and a power feeding part which is extended from the neighborhood of the end part of the glass plate, is connected to the thermal line part and feeds power to the thermal line part, and the power feeding part is partially narrowed.SELECTED DRAWING: Figure 2
【課題】熱線部をガラス板の端部から引き離しても、ガラス板の端部付近における熱応力の上昇を抑える技術を提供する。【解決手段】本発明の一側面に係る窓ガラスは、ガラス板及び導電性材料により形成され、前記ガラス板のいずれかの面に配置される導電性線条部を備える車両用の窓ガラスであって、前記導電性線条部は、前記ガラス板の端部から離間して配置され、前記ガラス板の所定の領域を熱するように所定のパターンを有する熱線部と、前記ガラス板の端部付近から延びて前記熱線部に連結し、前記熱線部に給電する給電部と、を備え、前記給電部は部分的に細線化されている。【選択図】図2
