<P>PROBLEM TO BE SOLVED: To provide a resin structure capable of effectively generating negative ions having beneficial effects on the human body. <P>SOLUTION: This resin structure contains a substance which generates the negative ions and is deformable by external force. The substance is preferably selected from tourmaline, diatomaceous earth, and a radioactive substance. The resin structure is formed into a thin rib-like shape and composed of a resin having elasticity, such as a silicone rubber, so as to be deformable. A writing material is formed by using the resin structure as its part. The resin structure is, for example, used as a cover for a grip and a knocked part of the writing material to which the external force is given. <P>COPYRIGHT: (C)2003,JPO |
