A circuit board and a manufacturing method thereof are provided to determine a present state of the circuit board, to secure high productivity and reduce fabrication costs. A circuit board(1) includes a base insulating layer, a conductor pattern on the base insulating layer, and a cover insulating layer for coating the conductor pattern on the base insulating layer. The conductor pattern includes a terminal portion(6) for being connected with an external terminal. The cover insulating layer includes an opening portion corresponding to the terminal portion. A position determining region is formed at a predetermined portion adjacent to the terminal portion in order to determine whether a peripheral portion of the cover insulating layer is located in proper position or not. |
