<p>PROBLEM TO BE SOLVED: To provide a circuit board which is easy to assure an electric conduction with a counterpart component and a connector mounted on the board. SOLUTION: A recess 4 is formed at an end face 1a of the circuit board 1. A wiring passage 3 is exposed to the outside via the recess 4. A protrusion 11 of the connector 10 is inserted into the recess 4, to thereby position the connector 10 on the board 1. Since the protrusion 11 is brought into contact with the passage 3, an electrical contact of the both can be assured.</p> |
