<p><P>PROBLEM TO BE SOLVED: To obtain a resin molded product widely and versatilely usable in a living space and enabling negative ions to be effectively generated in the living space. <P>SOLUTION: The resin molded product with woody tone and high favorableness in terms of appearance and mechanical strength and widely and versatilely usable in the living space and enabling negative ions to be effectively generated in the living space is obtained by incorporating a resin molded form with a microradioactive element substance. In this resin molded product, its function and durability can be improved by using the resin molded product having a two-layer structure consisting of a core part and a surface layer part and varying the wood flour formulating amounts and additive amounts in the core part and the surface layer part. Furthermore, this resin molded product can efficiently generate negative ions even with a small amount of the microradioactive element substance by incorporating it in only the surface layer part. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
