An electrochemical cell comprising:
- 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, wherein
- 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.
A manufacturing method of the electrochemical cell, comprising:
- a sealing process that seals a sealing portion of an outer circumference of a housing portion in which houses an electrode body;
- a fixing process that fixes a part of the sealing portion which is sealed in the sealing process;
- and
- a molding process that bends other portion of the sealing portion that is not fixed in the fixing process, while the fixing process is being performed.
