Stereo camera

The present invention provides a highly reliable stereo camera in which it is possible to prevent the heat generated by an image processing element from contributing to an increase in the temperature of an image sensor, even if the stereo camera is made more compact and the heat density is thus increased inside the stereo camera. The present invention includes: a pair of image sensors 106 that have respective imaging elements disposed at the same height with a space therebetween; image processing elements 109 that are disposed between the image sensors and process image signals captured by the image sensors 106; a casing 105 that has the image processing elements and the image sensors incorporated therein, and in the area between the image sensors, has an inclined surface that is inclined from the image sensors 106 downward toward the imaging direction of the image sensors 106; an airflow path 301 that is defined so as to extend along the inclined surface of the casing 105 toward the imaging direction; and heat dissipating parts 120 that are thermally connected to the respective image processing elements 109 and disposed on the inclined surface so as to face the airflow path.
