<p>PURPOSE:To provide a printed board wherein the mounting density of a board is not decreased, and unwanted electromagnetic emission can be suppressed. CONSTITUTION:A part 101 of a power supply planar layer 103 is separated. The separated power supply planar layer 101 is arranged on the other board 4 in the vicinity of a ground planar layer 102, and connected with the power supply planar layer 103, by using a connection means 109. Thereby the electrostatic capacity between the separated power supply planar layer 101 and the ground planar layer 102 is increased. Thereby a low-cost information processor is provided wherein the mounting density is not decreased and the energy of unwanted electromagnetic emission is low.</p> |
