PURPOSE: To provide an inspecting apparatus and an inspecting method for an illuminating optical element which efficiently inspect the illuminating optical element and reduce a manufacturing cost. CONSTITUTION: The inspecting apparatus 2 for lens arrays is provided with a light source apparatus 320 for radiating a parallel light flux, lens array holders 312, 313 for holding the lens arrays 113, 115 as subjects for separating the parallel light flex into a plurality of partial light flexes, and a frosted glass 170 for projecting optical images of the flexes radiated through the lens arrays 113, 115. A discarding frame corresponding to an illuminating region in design is formed on the frosted glass 170. The quality of the lens arrays 113, 115 is determined by existence of the region of the discarding frame included by the optical images projected on the frosted glass 170.
