Abstract
Provided is a secondary battery cell capable of reliably preventing an integrated circuit provided to the secondary battery cell from being removed from the secondary battery cell.
A secondary battery cell (20) includes an integrated circuit (IC chip) (50) that stores identification information (for example, identification number (ID number) given to the integrated circuit itself). The integrated circuit (50) includes a wiring abnormality detection circuit. When the integrated circuit (50) is removed from the secondary battery cell (20), the wiring abnormality detection circuit detects a wiring abnormality.
