1. A biological information detector for detecting biological information of an object person seated in a vehicle, comprising:
a reception antenna configured to receive radio waves transmitted from a transmission antenna, through the object person, wherein the transmission antenna is located outside the object person; and
a controller configured to:
acquire a reception signal corresponding to a radio wave received by the reception antenna when the radio waves are transmitted from the transmission antenna;
extract a signal component generated due to movement of a heart of the object person based on the received signal;
calculate a blood pressure of the object person as the biological information based on the signal component; and
output the blood pressure to a device that is located outside the controller and monitors the blood pressure of the object person; and
performing a route guidance of the vehicle based on the blood pressure.
