Abstract:
    A photodetector 50 having directional characteristics is obtained by arranging a photosensitive element 21 for a solar radiation sensor, a photosensitive element 22 for an illuminance sensor, and a light shielding part 42 in the same package constructed by a case and an optical lens as a cap. The photosensitive element 21 for a solar radiation sensor has two photosensitive parts which are formed apart from each other on the same plane, and outputs a detection signal according to an amount of solar radiation incident on the two photosensitive parts. The photosensitive element 22 for an illuminance sensor is disposed apart from the two photosensitive parts in the photosensitive element 21 for a solar radiation sensor, is formed in a region different from a border region of the two photosensitive parts, and detects illuminance above a vehicle. The light shielding part 42 is provided above at least the border region of the two photosensitive parts.
