A radome (1) for a vehicle-mounted radar device is provided with an electromagnetic-wave-permeable base material (3) and a base body (2) provided with heating wires (41) laminated on the inner surface side of the base material (3) and arranged in the surface direction of the base material (3), and in an electromagnetic-wave-irradiated region (R) of the base material (3), linear portions (411) of the heating wires (41) are arranged in parallel with a gap therebetween in the surface direction of the base material (3). The area occupancy of the linear part (411) of the heater wire (41) in the electromagnetic wave irradiation region (R) of the substrate (3) is set to be 1%-24% (inclusive). The radome can suppress the attenuation of electromagnetic waves irradiated by a vehicle-mounted radar device within an allowable range, and can play a practical snow melting function as a radome for a vehicle-mounted radar device.
车载雷达装置用天线罩(1)具有电磁波透过性的基材(3)和基体(2),所述基体(2)具备加热线(41),所述加热线(41)层叠配置于基材(3)的内表面侧而沿着基材(3)的面方向配置,在基材(3)的电磁波照射区域(R)中将加热线(41)的直线部(411)沿着基材(3)的面方向隔开间隔而并列设置,加热线(41)的直线部(411)的在基材(3)的电磁波照射区域(R)中的面占有率设定为1%以上且24%以下。能够将车载雷达装置照射的电磁波的衰减抑制在允许范围内并作为车载雷达装置用天线罩发挥实用的融雪功能。
