SHEET BODY

WIPO Patent Application WO/2020/096070

A1

The purpose of the present invention is to provide a sheet body that has an improved ice-accretion and/or snow-accretion inhibitory function. This sheet body comprises at least: an oil-containing resin layer that is in the form of a solid and that contains an oil; and an oil-permeable superficial resin layer which has a higher abrasion resistance than the oil-containing resin layer and which is laminated on one surface of the oil-containing resin layer. The oil contained in the oil-containing resin layer comprises a low-temperature exudative oil component that is capable of exuding from the oil-containing resin layer when the temperature drops to a level equal to or lower than a prescribed value, while the superficial resin layer exhibits oil permeability that allows the low-temperature exudative oil component exuding from the oil-containing resin layer to permeate the superficial resin layer up to a surface that is situated on the side opposite to the oil-containing resin layer.
