In a pattern inspection apparatus inspecting a pattern formed on a device and the like with a plurality of inspection lights, a sensitivity adjustment method in which respective optical systems associated with the inspection lights are efficiently and precisely checked to adjust the sensitivity thereof is attained. The sensitivity adjusting method for adjusting sensitivity of the pattern inspection apparatus performing inspection with a plurality of inspection lights includes the steps of preparing a sensitivity adjusting substrate divided into a plurality of regions to which identical reference patterns are provided, and scanning the reference patterns with the plurality of inspection lights making one of the plurality of inspection lights respectively correspond to one of the reference patterns, after attaching the sensitivity adjusting substrate to the pattern inspection apparatus. |
