Electronic apparatus

An electronic apparatus comprising:

• a conductive member;
• and
• a printed circuit board;
• wherein the printed circuit board has:
• a printed wiring board having a signal wiring formed thereon;
• a first semiconductor device;
• and
• a second semiconductor device connected to the first semiconductor device via the signal wiring,
• wherein the signal wiring has a signal wiring pattern formed on a surficial layer located opposite the conductive member in the printed wiring board,
• wherein the conductive member has an aperture forming portion in which a plurality of apertures formed therein at intervals from each other and located opposite the signal wiring pattern,
• wherein at least a part of the signal wiring pattern is formed to extend in a linear fashion, and
• wherein the aperture forming portion has a length in a direction perpendicular to a wiring direction in which the signal wiring pattern extends, the length being obtained by adding a wiring width of the signal wiring pattern to a length that is 6 times or more to 20 times or less a distance between the printed wiring board and the conductive member.
