<p><P>PROBLEM TO BE SOLVED: To provide a wiring substrate hard to misidentify a foreign substance as an alignment mark even when a protrusion distance of the alignment mark is small. <P>SOLUTION: A wiring substrate has a conductor wiring 3 formed on a surface of an insulating base material, a protrusion electrode 4 formed over both sides of the conductor wiring across a longitudinal direction of the conductor wiring, a metal pattern 5 formed so as to be extended in the same direction of a part in which the protrusion electrode is formed in the conductor wiring, an alignment mark 6 formed over a region on the insulating base material at both sides of the metal pattern across a longitudinal direction of the metal pattern, and a misidentification detecting pattern 7 formed so that the metal pattern is extended in a shape protruding in a direction across the longitudinal direction of the metal pattern at a position spaced apart from the alignment mark by a prescribed distance. When a foreign substance adjacent to the alignment mark 6 is erroneously recognized, the misidentification detecting pattern 7 is entered in a recognition image 9 to reduce a matching rate with a reference pattern 10 of a recognition apparatus, and as a result, the misidentification caused by the foreign substance can be prevented. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
