PROBLEM TO BE SOLVED: To provide a circuit pattern board in which the type thereof can be determined automatically even if the difference of pattern or material is little and error can be prevented in the functional inspection or assemblage. SOLUTION: Circuit pattern boards MT1A, MT2A having a circuit pattern formed on a board is provided with identification patterns 11, 12 where a plurality of lands p0, p1, p2, p3 comprising a conductive layer connectable with terminals externally and individually are arranged proximately to each other and connected, in different combinations, with power supply lines Vcc GND of different voltage depending on the type of the board.
