PROBLEM TO BE SOLVED: To obtain an ore composition enabling a person to readily and effectively have a share in the bounty of a radium ore or the like at his home by forming a sheet-shaped member by using the radium ore as an essential component and mixing other useful ores therewith; to provide a sheet material containing the ore composition; and to provide the sheet-shaped member using the sheet material. SOLUTION: The ore composition is constituted by mixing powder of one or more ores selected from feldspar, zeolite and tourmaline with powder of the radium ore. The sheet material is formed by allowing a paper sheet, a felt, a resin, a cardboard or a rubber material to contain the ore composition, or mixing them with the ore composition, and forming the product into a sheet shape. The holding of the ore composition can be carried out by packing many small chambers with the ore composition. The sheet-shaped member is obtained by forming an air-permeable layer and/or a waterproof layer on front or back one surface of the sheet material. COPYRIGHT: (C)2004,JPO
