To provide a printed circuit board and a printing method therefor which ensure the detection of a board body casted erroneously into a printing apparatus.
The printed circuit board body A is provided with respective target marks 30 which are arranged to be non-point symmetrical with respect to the plane diagonal intersection P0 of the board body A. The target marks 30 are formed primarily to improve precision in printing a circuit pattern, and are detected by an image processor 25 to detect not only a shift in the position of the board body A but also a shift in the direction of the board body A from a specified direction, which results from the rotation of the board body A with respect to the diagonal intersection P0. This ensures the detection of the board body A casted erroneously into the printing apparatus 20 without inviting a cost increase.
