Abstract
According to one embodiment, a printed wiring board includes an insulating layer, a first conductor pattern on the insulating layer configured to be a signal line, and a second conductor pattern on the insulating layer. The second conductor pattern includes a larger conductor area than the first conductor pattern, and a slit which allows the second conductor pattern to stretch to follow a thermal expansion of the insulating layer.
