Abstract
A protection circuit board includes a printed circuit board having a circuit is printed on a board formed from an electrically insulating material and two or more connection components disposed on at least one surface of the printed circuit board and are coupled to an electrode terminal of a secondary battery. Additionally, at least one inspection slot having a shape recessed within the connection component and extending to a portion that the electrode terminal of the secondary battery is coupled thereto and is defined in the connection component. Also, an inspection device and inspection method for inspecting a welded state between a protection circuit board and an electrode terminal among a pair of electrode terminals of a battery pack are provided.
