Abstract
A producing method of a wired circuit board includes the steps of applying light from above the wired circuit board toward the wired circuit board, and sensing pattern reflected light which is the light reflected by a conductive pattern, table reflected light which is the light reflected by a support table via an insulating layer exposed from the conductive pattern, and foreign-matter reflected light which is the light reflected by a foreign matter present on the insulating layer to inspect the conductive pattern and the foreign matter based on a contrast therebetween. A reflectance of the table reflected light is in a range of 30 to 70%, and a reflectance of the foreign-matter reflected light is in a range of not more than 10%.
