STEREO CAMERA DEVICE

Provided is a stereo camera device in which the temperature difference between a pair of left and right imaging elements is small, and a temperature increase in the imaging elements can be reduced. The present invention comprises a first imaging element and a second imaging element, a first circuit element and a second circuit element disposed between the first imaging element and the second imaging element, and a casing for retaining the first imaging element, the first circuit element, the second circuit element, and the second imaging element in this order, a second distance from the center of the second circuit element to the center of the stereo camera device being greater than a first distance from the center of the first circuit element to the center of the stereo camera device in the direction connecting the first imaging element and the second imaging element, the distance from the center of the first circuit element to the center of the first imaging element being greater than the first distance, and the distance from the center of the second circuit element to the center of the second imaging element being greater than the second distance.
