Abstract
The purpose of the present invention is to provide a sheet body having an improved function of preventing icing and/or snow accretion. At least included are a solid oil-containing resin layer containing an oil and an oil-permeable surface resin layer that has higher wear resistance than the oil-containing resin layer and is layered on one of surfaces of the oil-containing resin layer. The oil included in the oil-containing resin layer includes a low-temperature exuding oil component capable of exuding from the oil-containing resin layer when a temperature decreases to a predetermined value or lower, and the surface resin layer has enough oil permeability to permeate the low-temperature exuding oil component exuding from the oil-containing resin layer to a surface of the surface resin layer that is opposite to a side of the oil-containing resin layer.
