PURPOSE: To provide a liquid flow-down guide member provided with gas permeation and waterproof performance which can realize stable binding flow-down at all times without reducing its performance due to the condition of bonded surface and effect of wind greatly and restricting its use. CONSTITUTION: A liquid flow-down guide member consists of a basic material which is provided with gas permeation property, but prevents liquid from passing through it and a liquid absorption raw material 2 provided on the upper section of the basic material. The liquid absorption raw material 2 has a main flow- down path 4 which has a small liquid content amount, forms a stream of exposed liquid in which a part of liquid which flows down is absorbed and the remaining part slides on its surface, and has an arbitrary width and an auxiliary flow-down path 5 which is in the upper section of the basic material, is positioned on a side of the main flow-down path, and has larger liquid impregnation hold amount than the main flow-down path. While a stream of liquid along the main flow-down path 4 and the auxiliary flow-down path 5 is formed, a stream of the main flow-down path 4 is bound due to a difference in flow rate. |
