<P>PROBLEM TO BE SOLVED: To provide an ultralow-frequency generating apparatus having an electromagnetic wave shielding function, which is capable of guiding a brain wave to a desired value by removing environmental factors such as an electromagnetic wave. <P>SOLUTION: The apparatus is provided with a power source grounding detecting unit 10 for detecting the presence or absence of an existing power source grounding, and performing a grounding function; an ultralow-frequency generation control unit 20 for generating a δ wave or an α wave upon confirmation of the grounding state of the unit 10; an ultralow-frequency inducing conductivity body 30 for selectively inducing the δ wave or the α wave generated from the unit 20 to a human body. With this constitution, the scattering of a brain wave generated due to the influence of an adjacent electromagnetic wave can be prevented by the above grounding apparatus. <P>COPYRIGHT: (C)2004,JPO&NCIPI
