<p>PURPOSE: To achieve pharmaceutical effect and medical effect due to far infrared rays other than the mere use as a cushion by closing a laminated sheet consisting of a nonwoven fabric, a ceramic sheet and an air permeable sheet in a bag shape so that the nonwoven fabric is positioned on a surface side. CONSTITUTION: A laminated sheet 11 consists of a nonwoven fabric 12, a ceramic sheet 13, an air impermeable sheet 14 and a hot-melt sheet 15. The nonwoven fabric 12 and the ceramic sheet 13 are laminated by needle punching or an adhesive and, further, the air impermeable sheet 14 and the hot-melt sheet 15 are laminated by thermal fusion or an adhesive. Flexibility and pref. touch are imparted to the ceramic sheet 13 laminated by needle punching. As the nonwoven fabric, for example, a nonwoven fabric composed of a synthetic fiber such as a polyester fiber or a natural fiber is used. As the ceramic sheet 13, for example, a sheet obtained from a fiber slurry to which a ceramic powder composed of SiO2 or the like is added by a papermaking process is used. As the air impermeable sheet, for example, a polyvinyl chloride sheet is used.</p> |
