Abstract
A printed circuit board with reduced noise effects and without the need to increase the distance between a noise source and a wireless communication board. The circuit board includes multilayer structural conductive layers having a first conductive plane connected to power supply potential and a second conductive plane connected to ground potential. The first and second conductive planes are formed such that an electric field generated by a potential difference between the first conductive plane and the second conductive plane is concentrated on one side of one of the first conductive plane and the second conductive plane. The conductive plane associated with the concentrated electric field and the wireless communication board are on different sides relative to the conductive plane that is not associated with the concentrated electric field.
