  "textContent": "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 having a face having curvature. The light guide member (220) includes 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, the detection face (222) including a detection area where a part of the reflection light to enter the detection unit (206) passes through, and a non-detection area where remaining part of the reflection light not to enter the detection unit (206) passes through; a first intervening member (300) disposed on the detection face (222), a part or entire of the detection area attachable to a rear face of the light translucent member via the first intervening member (300); and a second intervening member (301), disposed on the detection face (222), a part or entire of the non-detection area attachable to the rear face of the light translucent member via the second intervening member (301). The first intervening member (300) has flexibility greater than flexibility of the second intervening member (301).",
