PURPOSE: To provide a printed wiring board in which a signal never deteriorates even if high-speed signal transmission is performed, and also the use efficiency can be improved by replacing only the fellow of a printed wiring board in the case where there is a defect in either printed wiring board. CONSTITUTION: This is a printed wiring board composed of printed wiring boards 1 and 2, and these two boards are connected with each other, with their circuit terminals 6 and 26 in contact with each other, and ground connector terminals 3 and 23 being used when the printed wiring boards 1 and 2 are overlapped on each other are both in mesh shape smaller in density of forming conductors than the ground layers 4 and 24. Moreover, the ground connector terminals 3 and 23 are connected witch each other at through holes 5 and 25. |
