A light guide member (220) useable for an object detection apparatus (101) is devised. The object detection apparatus (101) includes a light source unit (210), and a detection unit (206) for detecting an object adhered on a surface of a light translucent member, configuring a vehicle, based on change of light quantity of reflection light received from the light translucent member when light exiting from the light source unit (210) is reflected from the light translucent member. The light guide member (220) includes an incident face (223) where the light exiting from the light source unit (210) enters; a detection face (222) where the exiting light exits to a rear face of the light translucent member and the reflection light reflected from the light translucent member enters; an exiting face (224) where the reflection light exits to the detection unit (206); and a light guiding portion (227) through which the exiting light and the reflection light proceed. The detection face (222) has curvature corresponding to curvature of the light translucent member. |
