A continuity testing apparatus includes open/short detection circuits provided for to-be-tested terminals, respectively and configured to determine the presence or absence of at least any one of an open-circuit failure and a short-circuit failure in to-be-tested terminals. Then, the continuity testing apparatus generates detected results of the open/short detection circuits based on the condition of continuity of the to-be-tested terminals having connections to the open/short detection circuits and the detected results from the open/short detection circuits in the preceding stages, and outputs the generated detected results to the open/short detection circuits in the succeeding stages. Further, the continuity testing apparatus determines the condition of continuity based on the output from the open/short detection circuit in the last stage.
