Photodetector with improved appearance design and vehicle including photodetector of the same comprising a plurality of electronic components mounted on a light receiving surface side of a printed circuit board

A photodetector to be installed in a vehicle, the photodetector comprising:

• a case comprising a light receiving surface provided on an upper surface, the light receiving surface having a first region that transmits visible light and a second region that transmits less visible light than the first region;
• a printed circuit board mounted to face the light receiving surface;
• and
• a plurality of electronic components mounted on a light receiving surface side of the printed circuit board, the plurality of electronic components comprising a first light receiving element configured to detect visible light,
• wherein the first light receiving element is disposed at a first position of the printed circuit board, the first position being exposed to the visible light transmitted through the first region, and the number of mounted electronic components disposed at the first position is smaller than the number of mounted electronic components disposed at a second position of the printed circuit board, the second position being other than the first position.
