To provide a vehicle width detector with which it is possible to find a vehicle width when the vehicle as a detection object is seen from a camera.SOLUTION: A vehicle width detector 1 comprises: a camera 10 for imaging the surroundings of a vehicle; an image acquisition unit 20 for acquiring the imaged image imaged by the camera 10; a vehicle detection unit 21 for detecting a vehicle seen in the imaged image; a learned model storage unit 12 in which is stored a learned model having learned a relationship between a first projected vehicle width that is the vehicle width of the vehicle projected to a plane perpendicular to a direction from the lens main point of the camera 10 and the image of the vehicle; and a projected vehicle width inference unit 23 for applying the image of the vehicle detected by the vehicle detection unit 21 to the learned model and inferring the first projected vehicle width of the vehicle.SELECTED DRAWING: Figure 1
