Abstract
A printed circuit board includes a first mark 2 formed by a thin conductor, a second mark 3 formed by a resist 8, a land 6 which is partially coated by the resist 8 and a land 7 which is not coated by the resist 8. The second mark 3 is formed when the land 6 is partially coated by the resist 8. A device 4, which corresponds to the land 6, is mounted at a position apart from a center 02 of the second mark 3 by a predetermined distance L1. A device 5, which corresponds to the land 7, is mounted at a position apart from a center 01 of the first mark 2 by a predetermined distance L2. Therefor, the devices 4, 5 can be properly mounted on the printed circuit board 1 in spite of a positional error of the resist 8.
