PURPOSE:To eliminate errors of checking, enhance the workability by simplifying the checking operation of a circuit after a laminated printed circuit board is mounted in an electronic apparatus. CONSTITUTION:Cut grooves 4, 4' which cross positions of wiring patterns 22, 23 formed on circuit boards 11, 12, 13 are made near one end of a laminated printed circuit board 5 thereby to form a bendable removing piece 5', and a mark indicating the checking contents is printed on the upper surface of the piece 5'. |
