PROBLEM TO BE SOLVED: To provide an electrochemical element with improved sealing property and leakage resistance between a terminal and an outer easing. SOLUTION: For the electrochemical element, a macromolecule with functional group covalently and /or coordinately bonded to metal interposes at a sealing part 22 where an outer easing 20 and terminals 13, 14 are facing each other. The macromolecule is polyolefin resin or polycarbodiimide with structural unit derived from silane compound. |
