<p><P>PROBLEM TO BE SOLVED: To provide a printed wiring board capable of decreasing an influence of noise without increasing the distance between a noise source and a radio communication substrate, and an information processing apparatus for realizing miniaturization, an improvement of the throughput of radio communication and the extension of radio communication distance by applying the wiring board to an information processing apparatus with a radio communication function. <P>SOLUTION: The printed wiring board on which a radio communication substrate 40 is mounted has a multi-structural main circuit board 30 including a conductive plane 32 connected to a power source potential and a conductive plane 75 connected to a ground potential. The conductive planes 32, 75 are arranged so that the conductive plane 32 intervenes between the conductive plane 75 and the surface of the printed wiring board where the radio communication substrate 40 is mounted, and are formed so that an electric field generated from the difference in potential between the power source potential and the ground potential is concentrated on the conductive plane 75 side rather than the conductive plane 32. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
