Abstract: A biological information detector detects biological information of an object person. The biological information detector includes a reception antenna that receives radio waves transmitted from a transmission antenna through the object person, and a signal acquisition unit that acquires a reception signal corresponding to a radio wave received by the reception antenna when the radio waves are transmitted from the transmission antenna. The biological information detector further includes a calculation unit that calculates the biological information based on the received signal acquired by the signal acquisition unit. The calculation unit extracts a signal component generated due to movement of a heart of the object person based on the received signal, and calculates a blood pressure of the object person as the biological information based on the signal component.
