Abstract
Provided is a battery capable of surely interrupting current at the time of temperature rise so that excessive heat generation does not occur at the occurrence of an abnormality. The battery 1 includes a battery element 10 including a positive electrode and a negative electrode, an inner package 13 which forms a first chamber 13a for enclosing the battery element 10, an outer package 14 which encloses the inner package 13 such that the outer package 14 forms a second chamber 14a which surrounds the first chamber 13a, and a pair of terminals 11, 12 electrically connected to the positive electrode and the negative electrode and led out to the outside of the outer package 14. One terminal 11 of the pair of terminals 11, 12 has a first terminal 11a and a second terminal 11b arranged so as to be electrically connected in the second chamber 13a. A gas generating material 14 which generates gas at a predetermined temperature or higher or a predetermined voltage or higher is enclosed in the first chamber 13a or the second chamber 14a.
