Abstract
An object detecting apparatus comprises a case, a light radiation unit and a light receiver unit. The case has a light radiating window and a light receiving window. The light radiating window has a hydrophilic layer on the outermost surface of the light radiating window. The hydrophilic layer restricts water droplets remaining on the light radiating window from functioning as light collecting lenses, so that the light is radiated outward without being scattered by the water droplets. Specifically, the light radiating window further has a glass substrate at an innermost side and a photo-catalyst layer between the glass substrate and the hydrophilic layer. The hydrophilic layer is made of silicon dioxides.
