To provide an abnormality detection device, an abnormality detection method, and a program for easily specifying an abnormality location.SOLUTION: An abnormality detection device comprises a blower 22, a plurality of electronic apparatuses 20, and a control unit having a derivation unit and a specification unit. The blower 22 sends air W into a housing 15. The plurality of electronic apparatuses 20 are arranged in the housing 15 and aligned in parallel in a second direction Y crossing a first direction X in which the air W flows. The derivation unit derives a pressure difference between a first pressure on the upstream side in the first direction X from the plurality of electronic apparatuses 20 and a second pressure on the downstream side in the first direction X from the plurality of electronic apparatuses 20 in the housing 15. The specification unit specifies an abnormality location in the housing 15 based on the pressure difference and an estimated static pressure that is an estimated value of a static pressure in the housing 15.SELECTED DRAWING: Figure 1 【課題】異常箇所を容易に特定する、異常検出装置、異常検出方法、およびプログラムを提供する。【解決手段】異常検出装置は、送風機２２と、複数の電子機器２０と、導出部及び特定部を有する制御部と、を備える。送風機２２は、筐体１５内に風Ｗを送る。複数の電子機器２０は、筐体１５内に配置され、風Ｗが流入する第１の方向Ｘに対して交差する第２の方向Ｙに並列に配列されている。導出部は、筐体１５内における、複数の電子機器２０より第１の方向Ｘの上流側の第１の圧力と、複数の電子機器２０より第１の方向Ｘの下流側の第２の圧力と、の圧力差を導出する。特定部は、圧力差と、筐体１５内の静圧の推定値である推定静圧と、に基づいて、筐体１５内の異常箇所を特定する。【選択図】図１
