PROBLEM TO BE SOLVED: To provide a biological state acquisition device capable of acquiring a respiratory signal by a simple method compared with a prior art.SOLUTION: The biological state acquisition device comprises: signal reception/transmission means for transmitting an electromagnetic wave to a body surface of a living body, and receiving a reflection wave reflected on the body surface of the living body as a reception signal; orthogonal detection means for applying orthogonal detection to the reception signal to generate an I signal and a Q signal; IQ signal acquisition means for sequentially acquiring the generated I signal and Q signal in time series; and signal processing means for, based on direction change in a constant period of velocity vectors of the I signal and Q signal acquired in a prescribed time point on an IQ plane, generating a respiratory signal indicating change of respiratory of the living body as biological information. The signal processing means calculates the direction change in the constant period of the velocity vector on the IQ plane, as a cosine of an angle formed by the velocity vector on the IQ plane at the prescribed time point, and the velocity vectors on the IQ plane of the I signal and Q signal acquired in the past for a constant period.SELECTED DRAWING: Figure 1
