Abstract

An apparatus for inspecting a coated electrode sheet for a secondary battery. The apparatus comprises: a radiation emitting part configured to emit an x-ray or a beta ray towards the coated electrode sheet; a radiation detecting part, disposed opposite the radiation emitting part so as to have the coated electrode sheet positioned therebetween, wherein the radiation detecting part is configured to detect an amount of the x-ray or the beta ray emitted by the radiation emitting part and transmitted through the coated electrode sheet, to thereby gauge the thickness of the coating; a first protective layer disposed between the coated electrode sheet and one of the radiation emitting/detecting parts to cover a surface of said one of the radiation emitting/detecting parts facing the coated electrode sheet; and a controller configured to relatively move the first protective layer parallel to said surface facing the coated electrode sheet, either at a predetermined constant speed or periodically by a preset length.
