Document Type and Number:
WIPO Patent Application WO/2018/110465
Kind Code:
A1
Abstract:
Provided is a windshield 1 suitable for preventing fogging of a glass plate in contact with a light exposure space and maintaining information obtained by an information obtaining device at a high degree of accuracy. An absorptive membrane 81 or an antifogging member 8 having the same is disposed on at least one surface which is in contact with a light exposure space and selected from among a glass plate 5 and members 61, 62 that fix an information obtaining device 2 and/or shield light in a light exposure space 41. A saturated absorption amount Ws of the absorptive membrane is 1 g/m2 or higher. The absorptive membrane satisfies at least one selected from among: a condition A1 in which an adsorption isotherm of vapor forms a downwardly convex curve at 20-90% relative humidity; and a condition B1 in which the increase AbH in the amount of absorption when relative humidity is increased from 70% to 95% is greater than 35% of Ws.
