1. A radome for an on-board radar device comprising:
heater wires wired in parallel so as to be separated from each other in a plane direction of an electromagnetic-wave-transmitting base member, wherein
a line pitch of the heater wires arranged in parallel in an electromagnetic-wave transmission region of the base member is set to 0.2 to 2.5 times a wavelength of electromagnetic waves of a radar of the on-board radar device, and
a surface occupancy rate of the heater wires arranged in parallel in the electromagnetic-wave transmission region of the base member is set to be greater than 10% to 35%.
