In a passenger detection device (10), a vehicle interior image acquisition unit (11) acquires a vehicle interior image, which is an image that captures the vehicle interior. A face detection unit (12) searches for human faces in the vehicle interior image and specifies positions of detected faces. A biological entity information acquisition unit (13) acquires biological entity information inside the vehicle detected by an electromagnetic wave sensor (22). A biological entity detection unit (14) searches for biological entities present in the vehicle on the basis of the biological entity information and specifies the positions and sizes of the detected biological entities. A passenger determination unit (15) determines whether passengers are present in the seats of the vehicle and determines properties of the passengers in each seat, on the basis of the positions of the human faces and of the positions and sizes of the biological entities.
