A secondary battery is provided. The secondary battery includes an outer package (11); an electrode structure (20) contained inside the outer package, wherein the electrode structure includes an anode (22) and a cathode (21); an electrolytic solution contained inside the outer package, and a safety valve mechanism (15) configured to interrupt a current in accordance with an internal pressure of the outer package, wherein at least one of the non-impregnation electrolytic solution is in an amount so as to increase an operation probability of the safety valve mechanism and the anode includes a material that electrochemically generates gas at an anode potential so as to increase an operation probability of the safety valve mechanism.
