Solution: A secondary battery state detecting device (1) that detects a state of a secondary battery (14) installed in a vehicle, the device including: a learning means (control unit (10)) that learns element values of an equivalent circuit of the secondary battery (14) on the basis of a voltage and a current of the secondary battery (14); and a determination means (control unit (10)) that compares the element values obtained through learning at different timings by the learning means and, when at least one of the element values has changed more than or equal to a predetermined threshold value, determines that the secondary battery (14) has been replaced.",
