Zusammenfassung:	PURPOSE: A circuit board with marks indicating bad patterns and manufacturing method of a circuit board are provided to detect a position of a defective pattern unit included in a circuit board by scanning a marking unit. CONSTITUTION: A circuit board comprises a pattern unit(10), a rail(20), groove portion(41,42), and marking unit(31,32). The pattern unit comprises a plurality of pattern units. The rail is expanded along the edge of the pattern unit. The groove portion is formed at a predetermined location of the rail unit. The marking unit is formed in the groove portion. The marking unit shows the location of defective pattern units. The rail unit comprises a width extension unit(21). The width extension unit is expanded along in a row of the pattern units.
