PROBLEM TO BE SOLVED: To provide a printed wiring board including an identification mark which is easily confirmed with naked eye and is automatically recognized by an instrument such as an image processing apparatus in a manufacturing process of the printed wiring board with respect to a method for identifying the kind and order of substrates of printed wiring boards used in electronic instruments or the like, and further to provide its identifying method. SOLUTION: The identification method of the printed wiring board is adapted such that in the manufacturing process of the printed wiring board the identification mark is formed by partly scraping away the one side end surfaces of the boards, to permit a V shaped identification pattern to appear on the same surfaces of the boards in the state of the same where they are stacked up to a predetermined number of the boards. From the information of measured values of the position of the identification mark, the kinds of the printed wiring boards and the order of stacking thereof are extracted and identified.
