Provided is a windshield 1 suitable for preventing fogging of a glass sheet facing a light path space and for maintaining high accuracy of information acquired by an information acquisition device. A water-absorbing film 81 or an anti-fogging member 8 including the water-absorbing film 81 is disposed on a surface in contact with a light path space 41, the surface being at least one selected from a surface of a glass sheet 5 and a surface of members 61 and 62 serving the function of fixing of an information acquisition device 2 and/or light shielding for the light path space. The water-absorbing film has a saturated water absorption Ws of 1 g/m2 or more. The water-absorbing film satisfies at least one condition selected from the condition A1 that a water vapor adsorption isotherm is a downwardly convex curve at a relative humidity of 20 to 90% and the condition B1 that an increase in water absorption AbH with increasing relative humidity from 70% to 95% is more than 35% of Ws.
