Abstract
A laminated sheet which contains a cross-linking foam material, and radiates far infrared so that it has heat-insulating and heat-retentive properties. The laminated sheet () has a three-layered structure including polyethylene foam () having a sheet shape that is one example of a cross-linking foam material in which a substance that radiates far infrared rays is mixed, non-woven fabric () having a sheet shape formed on a lower face thereof and a polyester film () formed on an upper face thereof. Since the laminated sheet of the present invention is allowed to radiate far infrared rays, it can greatly shorten the snow-melting time, etc., because of its heat reflection effects in comparison with a sheet made of a single material of non-woven fabric, and it also makes it possible to greatly improve heat-insulating and heat-retentive effects, and also to provide medical effects.
