1. A nonaqueous secondary battery, comprising:

  • a negative electrode containing at least one of a material capable of reversely inserting and extracting lithium and metal lithium as a negative electrode active material;

    a positive electrode containing lithium as a positive electrode active material;

    an electrolyte; and

    a heat resistant member provided between the negative electrode and the positive electrode and permeable to lithium ions while having heat resistance,wherein in a case where a set voltage preset to a voltage lower than a voltage at which the electrolyte starts to decompose is applied between the negative electrode and the positive electrode, deposited metal is bridged between the negative electrode and the positive electrode according to the set voltage.
