PURPOSE: Provided is a method for producing a computer monitor or television case comprising a material sufficiently emitting far-infrared ray which is beneficial to human body. CONSTITUTION: The method comprises the steps of (i) crushing a natural stone emitting far-infrared ray to produce fine particles having particle size of 300 mesh or more; (ii) adding 2-20 wt% of the fine particles to resin and mixing the mixture for 30 minutes to form a mixed material; (iii) firing the mixed material at predetermined temperature to form an injection molded chip; (iv) introducing the injection molded chip into drier to dry the chip; (v) heating the dried chip at high temperature and introducing the chip into mold; (v) applying a high pressure to the molded chip introduced into the mold to produce a case emitting far-infrared ray.
