Abstract
A radome for on-board radar devicesis provided with heater wireswired in parallel so as to be separated from each other in a plane direction of an electromagnetic-wave-transmitting base member. A line pitch d of the heater wiresarranged in parallel in an electromagnetic-wave transmission region R of the base member is set to 0.2 to 2.5 times a wavelength of electromagnetic waves of the radar of an on-board radar device. A surface occupancy rate of the heater wiresarranged in parallel in the electromagnetic-wave transmission region R of the base member is set to be greater than 10% to 35%. The present invention provides a radome for on-board radar devices with which it is possible to obtain an electromagnetic-wave transmission property required of a radome, and to melt snow satisfactorily with a high heater performance.
