    Abstract: To provide an electrochemical cell and a method of manufacturing the electrochemical cell capable of securing the electric reliability while simplifying the structure and reducing manufacturing man-hours and costs. The electrochemical cell includes an electrode group in which a positive electrode and a negative electrode are overlapped through a separator, a positive electrode container to which a positive electrode projecting portion of the positive electrode which projects from an overlapping portion with respect to the negative electrode is electrically connected and a negative electrode container to which a negative electrode projecting portion of the negative electrode which projects from the overlapping portion is electrically connected as well as demarcating a housing space which houses the electrode group with the positive electrode container, in which a conductive material containing a carbon-based material is interposed between the positive electrode projecting portion and the positive electrode container.
