To provide a defogging device capable of achieving uniform temperature distribution in a field angle region of a camera.SOLUTION: A defogging device 15 includes a heater wire 20 which generates heat by energization to heat a windshield 11. The heater wire 20 includes a plurality of parallel portions 212, 213, and 214 which has longitudinal intermediate portions located inside a field angle region α serving as a region for capturing an image by a camera 12, and which are substantially parallel to each other. The plurality of parallel portions 212, 213, and 214 includes the two mutually adjacent parallel portions 212 and 213 which have longitudinal one ends connected to each other by connection portions 232 and 233 outside the field angle region α, but which have the other ends separated without being connected to each other. The other ends of the two mutually adjacent parallel portions 212 and 213 are connected to heat-quantity supplement portions 261 and 262 which are located outside the field angle region α and project toward sides of the adjacent counterpart parallel portions.SELECTED DRAWING: Figure 2

    【課題】カメラの画角領域の温度分布を均一にできる防曇装置を提供する。【解決手段】防曇装置15は、通電によって発熱することによってウィンドシールド11を加熱するヒータ線20を有しており、ヒータ線20は、長手方向の中間部がカメラ12により画像を撮影する領域である画角領域αの内側に位置し互いに略平行な複数の並列部212,213,214を有しており、複数の並列部212,213,214には、長手方向の一端どうしが画角領域αの外側において接続部232,233により接続されているが他端どうしは接続されずに離間している2本の互いに隣接する並列部212,213が含まれており、2本の互いに隣接する並列部212,213の他端は、画角領域αの外側に位置しており隣接する相手側の並列部の側に向かって突出している熱量補充部261,262に接続されている。【選択図】図2
