Abstract
A printed circuit board includes a printed wiring board and a terminal board bonded to the printed wiring boards. These boards contain reinforcing fibers, and the directions of the reinforcing fibers in both boards are the same whereby coefficients of thermal expansion of both boards are substantially equal to each other. Thus, it is possible to prevent the circuit board from bending and to get a planar arrangement of electrode terminals in a case where the terminal board is bonded to the printed wiring board with solder.
