Abstract:
A printed circuit board and method of manufacturing the printed circuit board, including a first and second write wiring patterns, an end of a first line and an end of a second line of the first write wiring pattern are arranged on both sides of a third line of a second write wiring pattern. Circular connection portions are provided at the ends of the first line and the second line. Through holes are formed in portions of a cover insulating layer above the connection portions, respectively. First connecting layers made of copper, for example, are formed to fill the through holes of the cover insulating layer. A substantially rectangular second connecting layer made of copper, for example, is formed to integrally cover upper ends of the connecting layers. This causes the first and second lines to be electrically connected to each other through the first and second connecting layers.
