  "textContent": "According to a conventional technique, first, the positional relation between a lens (13a, 13b) and an imaging element (12a, 12b) is kept at each of left and right camera units, adjustment is made so as to eliminate the rotation-direction deviation of an imaging element (12a, 12b) from one surface of a member to which a lens (13a, 13b) and an imaging element (12a, 12b) are to be attached before fixing, and then that camera unit is attached to a reference member to thereby constitute a stereo camera. However, although this method can eliminate a mounting position deviation when left and right camera units only are taken into consideration, a problem is posed that deviation again occurs due to poor machining precision and assembly precision at the mounting surface between a camera unit and a member when a camera unit is mounted to a stay (11). According to this invention, mounting surfaces for mounting left and right imaging elements (12a, 12b) to a stay (11) are provided to directly position left and right imaging elements (12a, 12b) to the stay (11), whereby built-up tolerance between components is reduced and the positional mounting precision between imaging elements (12a, 12b) is improved.",
