Abstract:

A translucent cover (12) covers a light emitting element (41) and a light receiving element (42), and forms a portion of an outer surface of a vehicle. The light emitting element (41) emits detection light (L1) for measuring the distance to an object (200) positioned outside the vehicle. The light receiving element (42) outputs a light reception signal corresponding to an amount of incident light. An inner non-reflective coating layer (16) is formed on an inner surface (12a) of the translucent cover (12). An outer non-reflective coating layer (17) is formed on an outer surface (12b) of the translucent cover (12).
