To provide a secondary battery system capable of detecting operation of a cleavage valve regardless of an installation position of the cleavage valve.SOLUTION: The present invention relates to a secondary battery system comprising: a secondary battery including a cleavage valve which is cleaved on a specific condition; a conductive thin film which is installed on the cleavage valve; and a measuring instrument for measuring a voltage or resistance which is generated when a current is made flow to the conductive thin film. The conductive thin film may also be installed in contact with the cleavage valve, the conductive thin film may also be installed so as to close a duct, or a resistance value of the conductive thin film may also be 1 kΩ to 1 MΩ.SELECTED DRAWING: Figure 1 【課題】開裂弁の設置位置によらず開裂弁の動作を検知できる二次電池システムを提供する。【解決手段】特定条件により開裂する開裂弁を有する二次電池と、前記開裂弁の上に設置された導電性薄膜と、前記導電性薄膜に電流を流した時に生じる電圧または抵抗を計測する計測器と、を有する二次電池システムであり、導電性薄膜は開裂弁に接するように設置されていたり、導電性薄膜はダクトをふさぐように設置されていたり、導電性薄膜の抵抗値が１ｋΩ〜１ＭΩであったりしてもよい。【選択図】 図１
