The invention relates to an improvement in tourmaline known as a functional ore. In particular, the invention provides a composite having a novel formation in which a far infrared radiation emitting property and others among tourmaline's properties are effectively exploited, a novel process for producing the composite, and composite materials to be used therefore. The invention includes the composite combining and integrating the tourmaline powder with a magnetizable body so that a laminated or racemic structure is formed, the process for the production of the composite producing a molded body having a racemic structure composed of the tourmaline powder and a magnetizable powder by homogenously mixing and stirring the tourmaline powder with the magnetizable powder, solidifying or freezing by an appropriate means to form a molded body and subsequently magnetizing the magnetizable powder, and a coating liquid form of the composite material composed of the tourmaline and the magnetizable powder to be used for the composite of the invention and the process for the production thereof wherein the tourmaline powder, together with an appropriate adhesive, are homogenously mixed and stirred with the magnetizable powder to form the coating liquid having a racemic structure and finally the magnetizable powder in the coating liquid are magnetized.
