A radome 1 for an on-board radar device is provided with a heater wire 3 arranged in parallel lines with a space therebetween in a surface direction of a substrate having an electromagnetic-wave transmission property. The line pitch d between the parallel lines of the heater wire 3 in an electromagnetic-wave transmission region R of the substrate is set 0.2 to 2.5 times the wavelength of electromagnetic waves of the radar of the on-board radar device. The surface occupancy of the parallel lines of the heater wire 3 in the electromagnetic-wave transmission region R of the substrate is set greater than 10% and less than or equal to 35%. The present invention provides the radome for the on-board radar device with which it is possible to obtain an electromagnetic-wave transmission property required of a radome, and to melt snow effectively with a higher heater performance.
车载雷达装置用雷达罩(1)具备以在电磁波透过性的基材的面方向上分离且并列的方式布线的加热器线(3),在基材的电磁波透过区域(R)并列的加热器线(3)的线间距d被设定为车载雷达装置的雷达的电磁波的波长的0.2~2.5倍,并且在基材的电磁波透过区域(R)并列的加热器线(3)的面占有率被设定为超过10%且35%以下。提供能够得到作为雷达罩所需的电磁波的透过性并且能够进行基于较高的加热器性能的良好的融雪的车载雷达装置用雷达罩。
