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.
Claims9
An electrochemical device comprising:
- a lid;
- a case having a via hole and forming a solution chamber between the case and the lid;
- an electric storage element accommodated in the solution chamber;
- an electrolyte accommodated in the solution chamber;
- a wiring having a via hole part which is provided in the via hole and connects an interior and exterior of the solution chamber;
- and
- a conductive bonding material layer fixing the electric storage element onto the case and electrically connecting the electric storage element and the via hole part, where the conductive bonding material layer has a contact area that contacts the case and a non-contact area that does not contact the case, and the non-contact area is formed within a parameter of the contact area in a manner surrounding the via hole as viewed from above.
