ABSTRACT:
A low-cost, fast and highly accurate defective wire detector is provided for detecting defects of wires in a wiring board at least having one wiring layer. The detector has a light emitting element substrate comprising a transparent substrate and a light emitting element arranged thereon. The light emitting element is, for example, an organic light emitting element or an organic light emitting diode. The light emitting element substrate is placed to be in contact with wires on a wiring board under measurement. The detector detects and processes a condition of light emitted from the light emitting element substrate when a voltage is applied between the light emitting element substrate and the wiring board, and determines whether or not any defective wire is present.
