To provide a tourmaline powder laminated sheet wherein a large amt. of tourmaline powder can be sticked lamellarly and a number of fine crystals are brought into contact with water molecules and a large amt. of surface active substances can be prepd.
A powder laminated sheet 1 is formed of a base material 2 and a tourmaline powder layer 3 sticking on this and the tourmaline powder layer 3 consists of a tourmaline powder 3a and an adhesive layer 3b. As the base material 2, such a material that prevents the tourmaline powder 3a from flowing out and has gas permeability is selected. The adhesive 3b is such an adhesive resin that partly adheres base materials together to form the tourmaline powder layer 3 which is not buried into a resin between the base materials 2. As water in the open air can passes through the tourmaline powder layer 3, the surface area of the powder which is brought into contact with the water molecules increases and the retention time in the layer becomes longer.
