PROBLEM TO BE SOLVED: To provide an inspection apparatus executing confirmation of lighting of a light-emitting element packaged on a substrate without any worker's determination. SOLUTION: The apparatus for inspecting an element 21 having current-voltage characteristics to be packaged on the substrate includes: a means 12 for increasing/decreasing current flowing to an inspecting element; a means 13 for reading voltage applied to the element; a means 11 for determining the current-voltage characteristics of the element and a combination of current-voltage changing according to a circuit block around the element for recording the result in a table; and a pass/fail determining means 11 for determining a combination of current flowing to the element by a current increasing/decreasing means and voltage read by a voltage reading means and applied to the element according to recording in the table for a plurality of times.
