Abstract
An electrochemical cell includes an electrode body which includes a positive electrode and a negative electrode and an outer package which is formed by overlapping a first member and a second member. The outer package includes: a housing portion which houses the electrode body; and a sealing portion which is formed along an outer circumference of the housing portion, by fusing and bending the first member and the second member, at a portion corresponding to the outer circumference of the housing portion.
