<p>The present invention provides a sunlight detection device provided with a housing (30) whose one side is open, a shadow member (32) which projects a shadow on a part of a base portion (31) inside the housing by sunlight entering from the opening surface of the housing, a scanning sensor (35a) which is an optical sensor disposed on the base portion and is used for scanning the sunlight illumination direction, and a minute sensing sensor (34a) which is an optical sensor disposed on the base portion and is used for minutely sensing the sunlight illumination direction. In a detection direction in which the sunlight illumination direction is detected, the minute sensing sensor is disposed to be in contact with the inside of a shadow boundary (C) of the shadow member projected on the base portion by the sunlight from the detection direction, and, at the same time, the scanning sensor is disposed outside the shadow boundary.</p> |
