Abstract
An electrochemical device has a lid, case, electric storage element, electrolyte, and conductive bonding material layer. The case has a via hole and forms a solution chamber between itself and the lid. The electric storage element is accommodated in the solution chamber. The electrolyte is accommodated in the solution chamber. The wiring has a via hole part provided in the via hole and connects the interior and exterior of the solution chamber. The conductive bonding material layer fixes the electric storage element onto the case while electrically connecting the electric storage element and via hole part, where the conductive bonding material layer has a contact area that contacts the case and non-contact area that does not contact the case and the non-contact area is formed in a manner surrounding the via hole.
