To secure detection accuracy of biological information even when the direction of the body of a passenger is changed.SOLUTION: A biological information device comprises: a transmission antenna 11a for transmitting radio waves toward the body of a passenger sitting in a vehicle sheet 50; and a reception antenna 12a for receiving the radio waves having passed through the body of the passenger. Furthermore, the device comprises a control unit 13 for detecting biological information about the living body of the passenger on the basis of a reception level of radio waves received by the reception antenna 12a. The transmission antenna 11a is disposed on a seat belt 20 holding the body of the passenger, the reception antenna 12a being disposed on the seat back 52 of the vehicle seat 50.SELECTED DRAWING: Figure 1

    【課題】乗員の身体の向きが変化した際でも生体情報の検出精度を確保できるようにする。【解決手段】車両シート50に着座する乗員の身体に向けて電波を送信する送信アンテナ11aと、乗員の身体を透過した電波を受信する受信アンテナ12aと、を備える。さらに、受信アンテナ12aによって受信された電波の受信レベルに基づいて乗員の生体に関する生体情報を検出する制御部13を備える。送信アンテナ11aは、乗員の身体を保持するシートベルト20に配置され、受信アンテナ12aは、車両シート50のシートバック52に配置されている。【選択図】図1
