Abstract
[Object] To provide an electrochemical device that permits a thin package, as well as securely prevents an electrolyte or gas in an internal space from leaking outside even when temperature rise occurs in the electrochemical device during the process where the electrochemical device is reflow soldered to a circuit board or encapsulated into an IC card. [Solution] In the electrochemical device RB, the main body of the package PA includes first cover plate, first terminal plate, frame plate, second terminal plate, and second cover platestacked in this order and bonded at the facing surfaces. The electric storage element SD is encapsulated in internal space IS formed, between the cover plates, by the through holesin the frame sectionsof the terminal platesand the through holein the frame plate
