PROBLEM TO BE SOLVED: To provide a lithium secondary battery with connection resistance and internal resistance little increased after it has been stored for a long period of time or in a high temperature condition. SOLUTION: In this lithium secondary battery, a positive electrode terminal 51, a flange part 52, a washer 54, a first nut 55, and a second nut 56 constitute an electrode terminal mechanism 5 on the positive-electrode side. Their surfaces are covered with coating layers 51a, 52a, 54a, 55a and 56a, respectively, made of a ceramic material containing a transition metal. |
