Abstract

An inspection apparatus is an inspection apparatus for inspecting a sample in which a plurality of light-emitting elements including a first light-emitting element and a second light-emitting element arranged around the first light-emitting element is formed, the inspection apparatus including an excitation light source that generates excitation light to irradiate the sample, a camera that images fluorescence from the sample, and a determining unit that calculates a relative luminance of fluorescence from the first light-emitting element based on the fluorescence from the first light-emitting element and fluorescence from the second light-emitting element imaged by the camera, and compares a calculated value based on an absolute luminance and the relative luminance of the fluorescence from the first light-emitting element with a predetermined threshold value, thereby determining a quality of the first light-emitting element.
