Claims

[Scope of Claim for Utility Model Registration] A photoelectric element that is provided with its light-receiving surface facing upward and that converts the intensity of incident light into an electrical signal and outputs it to a cooling control device; and a transparent body covering at least an upper part of the light-receiving surface, the sun sensor for an auto air conditioner for an automobile having a light-shielding body that blocks incident light that enters the transparent body from near the horizontal direction from reaching the light-receiving surface. A sun sensor for an auto air conditioner for an automobile, characterized in that a means is provided.
