PROBLEM TO BE SOLVED: To provide a printed circuit board which solves a problem of pattern disconnection and cost increase.SOLUTION: A printed circuit board of the present embodiment comprises a first pad and a second pad which lie adjacent to each other, and are electrically disconnected when separated and are electrically connectable when solder bonded. The first pad is formed such that a part opposed to the second pad has both ends projecting toward the second pad and a concave part between projected both ends. The second pad is formed such that a central part of a part opposed to the first pad lies so as to be sandwiched by both ends of the first pad and has a convex part projecting so as to lie within the concave part. In addition, a width of the convex part of the second pad is equivalent to or larger than a width of each of both ends of the first pad. |
