摘要： A printed circuit board (PCB) has a connection ground pattern and a wiring ground pattern. The connection ground pattern is a pattern for soldered connection formed on a first wiring layer. The wiring ground pattern is formed to be spaced from the connection ground pattern on the first wiring layer. The connection ground pattern and the wiring ground pattern are electrically coupled via a second wiring layer. When the wiring ground pattern is covered with an insulating layer, such as a solder resist, even if the position of an end of the insulating layer varies among wiring ground patterns, an influence on an exposed area of the connection ground pattern is eliminated.
