PROBLEM TO BE SOLVED: To equip a battery cell itself constituting a battery with a self diagnostic function and a bypass circuit formation function. SOLUTION: The battery cell 1 has an electrode plate part 6 housed in a conductive battery case comprising a case main body 2 and a lid 3, and the electrode plate part 6 is connected to a bottom part 2b of the case main body 2 by a negative electrode current collector 7. The electrode plate part 6 is connected to a positive electrode terminal 5 installed on the lid 3 through an insulator 4 by a positive electrode current collector 8. The positive electrode terminal 5 and the negative electrode current collector 7 are constructed of indium (In) which melts when the electrode plate part 6 of the battery cell 1 has an abnormal heat generation.
