The present invention aims to provide an optical axis ascertaining device for an in-vehicle camera which can simply adjust and correct the optical axis of the camera. This device comprises image processing device 2 (image recognition portion 20 and tracking portion 21) detecting a static obstacle (for example, wheel stopper disposed on ground surface) from an image acquired by rear camera 1 through image recognition and tracking the static obstacle and rear wheel rotation sensor 3 as a sensor detecting a movement distance of a vehicle, for example; and ascertains the optical axis direction of the camera, based on an attachment position of the camera and the movement distance of the vehicle from where a static object being tracked is out of an image capturable region of the rear camera 1 due to an approach of the vehicle to where the vehicle comes into contact with the static object.
