Abstract: A sunlight lens portion includes a low elevation angle surface for capturing light at low elevation angles, an opposing surface which is adjacent to the low elevation angle surface and which faces a sunlight detection element, and a high elevation angle surface for capturing light at high elevation angles. Further, the sunlight lens portion includes a reflection surface adjacent to the high elevation angle surface and the opposing surface. Accordingly, a portion of sunlight entering the sunlight lens portion is reflected by the reflection surface and guided to the sunlight detection element, therefore it is possible to broaden a range of peak sunlight amount detected by the sunlight detection element. Due to this, it is possible to reduce an effect of the angle of inclination of the windshield on the elevation angle characteristic of the sunlight sensor.
