PROBLEM TO BE SOLVED: To provide a deodorant manufacturing device using weathered coral to be used in a place where a dynamic external force such as a frictional force, or the like, exists. SOLUTION: Weathered coral gravel 1 is heated and sterilized by a heating sterilization means 2, or baked by a baking means and crushed by a fine crushing means 3. This sequence of heating and sterilization or baking and crushing may be reversed. If it is not baked, it is heated and sterilized, thereby providing a lasting effect of deodorization.
